How to Block and Frame a Finished Needlepoint Piece
Blocking a canvas back into square, wet or with steam, then mounting and framing it so that the glass never touches the stitches.
After the last stitch, a piece meant for the wall is usually blocked, then mounted and framed. Each of the three steps can be done at home or handed to a shop or a framer.
This guide starts with blocking: testing the threads, the wet method, the order the pins go in, and blocking with steam, which NeedlepointTeacher.com offers for threads that may run. Then it covers mounting the canvas flat, the mat and the glass, framing it yourself, what to ask a framer for, and where to hang the finished piece. A piece that will be sewn into something, such as a pillow or an ornament, is finished rather than framed, and our finishing guide covers that.
On this page: how to block needlepoint, testing the threads, what you need, wet blocking, the order of the pins, steam blocking, having a shop block it, mounting, the mat and the glass, framing it yourself, a professional framer, where to hang it, and the FAQ.
How to block needlepoint
Blocking brings a stitched canvas back into a true square or rectangle. DMC, the thread maker, describes it as squaring the canvas back into its original shape. Needlepoint.Com, which has shops in Charleston and Raleigh, adds in its guide to self-finishing that blocking fluffs up the stitches.
Stitching pulls a canvas out of shape. Unwind Studio, which sells needlepoint kits and frames, names continental tent stitch among the stitches that tend to distort it. Rittenhouse Needlepoint in Philadelphia, in its 2026 finishing price list, names conditions that affect its ability to square a piece. They include stitching without stretcher bars, a hoop, or a frame; very tight stitching; some man-made threads, Kreinik's for one, that resist stretching; and certain novelty stitches.
Block a piece before you frame it. Unwind Studio says a piece has to be blocked first, so that its edges sit straight inside the frame. Poppy Monk Needlepoint, which makes kits, says to block even a piece that looks straight, because a square frame makes a slight skew obvious.
Test the threads first
Water can make some threads run, and NeedlepointTeacher.com, the site of needlepoint teacher and author Susan Sturgeon Roberts, warns that the damage often cannot be undone. Test the threads before you block, whichever method you use.
Ellen Johnson, a needlepoint teacher, gives a test in a post on her site, Serendipity Needleworks, and suggests doing it before you start stitching. She moistens a white paper towel with warm water, lays a length of thread at least 2 inches long on it, folds the towel over, presses it down firmly, and waits at least ten minutes. If any dye has bled onto the towel, the thread is not colorfast. Test every thread in the piece: Johnson says colorfastness can differ even between dye lots of the same thread, and Poppy Monk warns, naming red, that some colors bleed even when the label calls them colorfast.
Clean a dirty piece before you block it. NeedlepointTeacher.com says never to block dirty needlepoint, and to have it cleaned professionally if it needs it. Silk calls for extra care: the same site says silk is sensitive to water and sunlight, and in its entry on Kreinik's Silk Bella it says not to wash or wet block silk projects.
What you need
- A blocking board. NeedlepointTeacher.com makes its own from medium-density fiberboard, 24 by 48 inches, which takes a piece up to 20 inches wide. It covers the board drum tight in white muslin and draws two lines on it at right angles. Poppy Monk uses grid-marked mats that lock together in 12-inch squares, and says they take water, where a board you make yourself could stain your needlepoint. Unwind Studio uses foam board.
- Pins. T-pins, since NeedlepointTeacher.com finds wig pins not strong enough. Poppy Monk uses brass tacks instead, which it says grip close to the canvas and give more leverage.
- A white terry towel, for rolling out a wet piece, and a spray bottle for misting.
- Something square. NeedlepointTeacher.com checks the corners with a 90-degree triangle or a sheet of paper; Unwind Studio uses rulers or a square.
For a large canvas, NeedlepointTeacher.com suggests canvas pliers, whose grooved teeth grip the canvas for stretching.
Wet blocking, step by step
These steps follow the wet method on NeedlepointTeacher.com, with DMC's instructions where they add to it.
- Face up or face down. Block a piece with raised stitches face up, and a flat one, such as a chair seat in basketweave, face down, so that it lies as flat as it can.
- Wet it. A wool piece can go into a tub of cold water; then roll it in a white towel and squeeze out the excess. Cotton and other threads are only misted, damp but not soaked, as you would dampen a shirt to iron it. DMC sprays the whole canvas with warm water instead, not enough to saturate it, and lets it rest for five minutes to relax the fibers.
- Ease it back by hand. A canvas pulled into a parallelogram is stretched gently on the bias, not with a hard tug. DMC says most stitched canvases lean to the right, and brings one back by holding its upper left and lower right corners and pulling the canvas back into a reasonable alignment.
- Pin it, in the bare canvas. The first pins go in the middle of each side, then out toward the corners, which take the last four. The figure below shows the order. If you are misting, NeedlepointTeacher.com goes on misting every five minutes as it pins. DMC dampens the canvas again if it starts to dry, and sets the pins about 3/4 inch apart, adding a few at a time to each side in turn.
- Check that it is square. Hold the triangle or the sheet of paper to each corner. If the sides are straight but the middle is not, NeedlepointTeacher.com pushes T-pins straight down into the canvas where it needs straightening. The site takes those middle pins out after four to six hours, and leaves the pins along the sides.
- Walk away, then look again. NeedlepointTeacher.com's advice is to leave it for a cup of espresso. Your brain can trick your eyes into seeing the canvas as straight, and after a rest you see it as it is.
- Let it dry flat. NeedlepointTeacher.com dries it for at least twenty-four hours, so that the colors cannot run to one side, and out of the sun, which fades thread. DMC says drying can take several days or longer, depending on humidity and temperature, and takes the pins out only when the canvas is bone dry. If the canvas relaxes into lumps or ridges after a day, stretch it again.
- Repeat if you need to. If the piece is still out of square once it is dry, NeedlepointTeacher.com and DMC both say to block it again, as many times as it takes.
The order the pins go in
Start at the middle of each side, so that the center of the stitched picture is pulled taut. NeedlepointTeacher.com numbers the pins in its own drawing: 1 at the top, 2 at the bottom, 3 on the left, and 4 on the right. Then come 5 to 12, one either side of each of those, and more pins outward along every side until the four corners get the last ones. DMC and Poppy Monk start in the same order, top, bottom, left, and right. Poppy Monk warns against starting at the corners: the canvas takes too much tension at an angle, buckles, and is likely to pull the tacks out.
The pins around the edge go into the bare canvas, not the stitching. Poppy Monk sets its tacks as close to the stitching as it can, for more leverage. DMC says never to cut the canvas before blocking, because the bare canvas around the stitching is what holds the pins.
Steam blocking
Not every piece can get wet. Rittenhouse wets a piece to block it only when the piece's threads are colorfast. Its price list says a badly skewed piece has a better chance of coming back to square when it is misted with water, and asks you to leave its colorfast box unchecked if you are not sure. Poppy Monk, whose own test blots a dampened scrap of thread on a paper towel, says to consider dry-blocking if color comes off, though it does not say how.
NeedlepointTeacher.com's answer is steam. Its wet method page says to use the steam method if you are not sure the threads can get wet. Its steam method page says the method can be used with silk, overdyed threads, and other threads that may run:
- Test any thread you are not sure of for colorfastness, as the site's own reminders for steaming say to.
- Mount the canvas on stretcher bars, as straight as you can get it.
- Bring a kettle of water to a boil. If your water is hard, use distilled or bottled water.
- Hold the stretcher bars about 8 inches over the steam, wrong side down, and move the canvas around very slowly, so that the steam goes through the stitches. Go on until you have steamed the whole piece, and never steam it too long.
- Lay the bars flat on a table to dry. The piece should be dry in about an hour, and the site says to wait an hour before taking it off the bars.
NeedlepointTeacher.com warns against a steam iron, which can spray drops of water that stain the threads. Unwind Studio does use one. It holds the iron just above the back of the canvas, never touching it, then stretches the canvas by hand, checks the corners with a square, pins it, and leaves it pinned for twenty-four hours. Unwind makes this its main method, and suggests wetting a piece lightly when it is stubborn.
The sources also disagree on steaming threads that may run. Ellen Johnson counts steam as a wet blocking method, and says a finisher should use no wet method, steam included, on threads that are not colorfast, or that you did not test before stitching. If you send out a piece with threads that might run, ask which method the finisher will use.
Having a shop block it
DMC suggests asking a local needlework shop to block a piece for you. In its 2026 price list, Rittenhouse charges $25 to block a piece of up to 16 square inches when no other finishing is ordered, and $80 for 200 to 350 square inches. When Rittenhouse finishes a piece, it blocks the piece once at no charge if the piece is visibly skewed. Its list warns against washing a piece yourself before it goes in: washing removes the canvas's starch, and a blocking then has trouble holding square. Rittenhouse's list prices cleaning and restoration by the hour, so if a piece needs cleaning first, ask the shop.
Rittenhouse also warns that a badly skewed piece may need more than one blocking, and that one blocked but not finished may drift back toward its old shape. Some stitching, it says, may never come completely square. Poppy Monk adds that a framer may block a piece for you, but that it pays to ask.
Mount it flat
A framed canvas needs something stiff behind it to keep it flat. Unwind Studio names three common ways of fixing needlework there: gluing, pinning, and lacing. It avoids glue, because glue limits what the piece can be finished as later.
- Pinned to foam board. Unwind Studio pins the blocked canvas to 3mm foam board with stainless steel dressmaker pins, which do not rust, pushed in so that their heads hide and their points stay out of the back. It centers the canvas so that only the stitching shows through the mat.
- Laced onto acid-free board. NeedlepointTeacher.com's lace method cuts an 8-ply acid-free museum board 1/8 inch smaller than the frame on every side, so that the canvas has room to fold over its edges, and covers the board in white fabric. It lines the canvas up by marks at the middle of each side, then laces the margins together across the back in zigzag stitches, one way and then the other.
- Sewn onto acid-free board. M. Finkel & Daughter, the Philadelphia dealer in antique samplers, mounts its own pieces by hand-sewing them onto acid-free museum board covered in fabric. The Canadian Conservation Institute (CCI) gives the same kind of mount for small, light textiles, stitched at the edges to a fabric-covered board. It says the mount supports the whole piece and can be undone without harming it.
- Stapled over stretcher bars. NeedlepointTeacher.com's staple method makes stretcher bars a little smaller than the inside of the frame. It staples the canvas on in the same order as the pins, the middle of each side first and the corners last, and folds the corners into miters. A mat finishes the edge, or, in its example, a ribbon.
The CCI separates framing where long-term preservation is not the main concern from framing an heirloom. In its notes on framing embroidery, it says a framer's usual materials and methods are all acceptable for the first, but that an heirloom needs archival ones. It lists what should never touch such a textile, among them glue, adhesive tape, staples, tacks, and nails, and notes that a piece on stretchers acts as an air filter and traps dirt. By that list, the staple method above suits a piece for display rather than an heirloom.
The mat, the spacers, and the glass
Glass should never press on the stitches. The CCI's word for the glass is glazing, which can be glass or plastic, and this guide says glass for either. The CCI raises the glass a little above the textile with spacers, so that raised stitching is not crushed, and says the gap also lowers the risk of moisture condensing on the glass in a cold, damp room. A mat can be the spacer. Where the mat covers part of the piece, as it covers the bare canvas around a needlepoint, the CCI raises it on narrower mats, so that its edge does not press into the textile.
M. Finkel & Daughter's framing also keeps the needlework spaced away from the glass. The firm seals its wooden frames and attaches the backing with archival tape. The CCI seals a frame with tape across the joint where the backing board meets it, and prefers gummed linen tape to the usual brown kraft tape, because the linen tape is more stable.
The mat's opening is the part to get right. Unwind Studio says the mat that comes with a frame usually does not match the stitched area. The opening has to match it, or blank canvas shows at the edges or the mat covers too much of the stitching. Measure the stitched area once the piece is blocked. A frame shop can cut a mat to size, or you can order one online or cut your own.
Glass is a choice. Unwind Studio calls it a personal one, which depends on the look you want and your budget, and says it keeps dust, dirt, and oils off the needlework. The CCI's note says glazing that filters out ultraviolet light gives some protection from light, though not complete protection. Of glass and plastic, glass is heavier and breaks more easily; plastic scratches more easily, and can build up enough static when it is wiped to pull loose threads toward it.
Unwind Studio recommends museum glass for its clarity and its control of reflections, and warns that it is very expensive. With a cheaper glass, it says, avoid one without UV protection. M. Finkel & Daughter says the conservation glass it uses blocks ninety-seven percent of ultraviolet light. Without glass, Unwind Studio says, a piece needs dusting, or dabbing with a damp cloth, and should hang away from smoke and cooking oils, which can stain it.
Framing it yourself
You can frame a piece at home in a frame bought from a store. Unwind Studio's framing guide shows two ways with frames from IKEA. In one, the canvas is pinned to foam board, as above, and set behind a mat that hides the bare canvas. In the other, it is wrapped around foam board a little smaller than the stitched area, so that no bare canvas shows at the folded edges, and taped to a backing mat, so that the needlepoint seems to float.
NeedlepointTeacher.com suggests planning ahead: buy the frame first, then stitch a piece to fit it, which saves cost and trouble. Its staple and lace methods, above, both end with the mounted piece set into the frame and brown paper over the back.
For small pieces, self-finishing blanks such as bookmarks and luggage tags skip framing altogether. Our starter supplies guide lists a few.
When to use a professional framer
For an heirloom, or any piece you want to last, the CCI says it is important to understand the difference between everyday framing and archival framing, and to know what to ask for. From its notes and the sources above, ask a framer for four things:
- a piece blocked square first, by you or by the framer;
- a mount that is sewn or laced onto a fabric-covered acid-free board, not glued;
- acid-free materials throughout, from the mats to the backing board;
- spacers that keep the glass off the stitching, and glass that filters ultraviolet light.
The CCI also suggests talking over the dimensions with the framer before the piece is mounted. Some pieces should go to a textile conservator before any framing at all. The CCI lists a piece glued to acidic board, and one with dyes that run, mold, insect damage, powdering threads, stains, adhesive residue, splits, tears, or losses.
Not every finished piece gets framed. A Christmas stocking is sewn into shape instead: see our stocking guide, and our finishing guide for what sewn finishing costs and how long it takes.
Where to hang a framed piece
Keep a framed piece out of the sun. The CCI says even a properly framed textile can fade and weaken in the wrong light and temperature, and UV-filtering glass protects it only in part. It advises watching where the sun falls in a room through the day and hanging the piece somewhere else. It also advises keeping the piece away from fireplaces, radiators, and heating vents, and off the outside walls of unheated buildings, which are cold and damp, and not attaching lights to the frame.
Unwind Studio adds that a humid room can make a framed piece warp, and NeedlepointTeacher.com that sunlight fades thread.
FAQ
Do I have to block my canvas before framing it?
Unwind Studio's framing guide says you do, so that the edges sit straight in the frame. Even a piece that looks straight should be blocked, Poppy Monk says, because a slight skew shows once a square frame surrounds it.
How long does needlepoint take to dry after blocking?
After wet blocking, NeedlepointTeacher.com leaves a piece to dry flat for at least twenty-four hours, and DMC says it can take several days or longer, depending on humidity and temperature. Take the pins out only when it is completely dry. A piece steamed by NeedlepointTeacher.com's method should be dry in about an hour, and Unwind Studio leaves a steamed piece pinned for twenty-four hours.
Can I block needlepoint without getting it wet?
Not by any method these sources describe. NeedlepointTeacher.com's answer for threads that may run is steam, but steam still dampens the canvas, as Unwind Studio's instructions say, and Ellen Johnson of Serendipity Needleworks counts it as wet blocking. Poppy Monk says to consider dry-blocking if a thread bleeds, but does not describe a method. Whatever you choose, test the threads first.
Can you block needlepoint with an iron?
The sources disagree. NeedlepointTeacher.com says not to use a steam iron, because it can spray drops of water that stain the threads, and steams a canvas over a kettle instead. Unwind Studio does use a steam iron, held just above the back of the canvas and never touching it.
Should I block needlepoint face up or face down?
NeedlepointTeacher.com blocks a piece with raised stitches face up, and a flat piece, such as a basketweave chair seat, face down.
What if my canvas is still crooked after blocking?
Block it again: NeedlepointTeacher.com and DMC both say to repeat the process as many times as it takes. Rittenhouse Needlepoint warns that some stitching may never come completely square, and that a badly skewed piece blocked but not finished may drift back, so plan to frame or finish it once it is square.
Can I frame needlepoint myself?
Yes. Unwind Studio frames pieces at home in frames from IKEA, and NeedlepointTeacher.com's lace and staple methods take you through mounting one yourself. Block the piece, pin or lace it onto a board, and set it behind a mat in the frame, with the glass kept off the stitching. For an heirloom, ask a framer for the archival materials and mount that the CCI describes.
Does a finished needlepoint piece need to be behind glass?
No. Unwind Studio calls glass a personal choice: it keeps dust, dirt, and oils off, and a piece without it needs dusting now and then. If you do use glass, keep it off the stitches with a mat or spacers, and choose one that filters ultraviolet light.
Ask a local shop which framer it recommends, or whether it frames in house.
