Finishing embroidery: washing, blocking and framing without ruining it

There is a sequence here and departing from it is what causes almost every ruined piece. Test, wash, block, dry flat, then mount. Each step exists to undo something the previous one did, and doing them out of order sets a problem in place permanently.

The commonest mistake is ironing first. A hot iron on a piece that has been in a hoop presses the hoop mark and the distortion into the fabric while the fibres are dry, which is precisely when they hold a shape. Washing and blocking would have removed both.

A thread that has run

Finished embroidery usually needs washing whether or not it looks dirty. Hands leave oils over weeks of handling, hoops leave a ring, and any transfer marking still in the fabric needs to come out — several kinds are designed to wash away and will otherwise stay visible forever under glass.

What actually matters:

• Test every colour first, on a tail — Take a spare length of each thread you used, wet it, and press it between two pieces of white cotton. If colour transfers, that thread will run. Reds and dark blues are the usual offenders, and hand-dyed and vintage threads are far less predictable than a branded stranded cotton. This takes five minutes and it is the only step here that prevents an unfixable outcome.
• Cool water, by hand, no rubbing — Warm water encourages dye to move. Submerge, move it gently, leave it, rinse. Rubbing a stitched surface felts wool and abrades floss.
• If a colour does run, do not stop — The instinct is to lift it out of the water immediately. That is backwards: loose dye needs somewhere to go, and taking the piece out leaves it in the fabric. Keep rinsing in cool running water until the water is clear.
• Never wring it — Press it between towels. Wringing distorts the ground fabric in a way blocking then has to fight, and it can pull long stitches out of tension.

Blocking is pinning the damp piece out square and letting it dry in that position. It is what turns a slightly bowed, hoop-marked rectangle into something flat enough to frame, and it is the difference most people are seeing when they say a piece looks finished.

You need a surface you can pin into that will not stain when wet — a cork board covered in a clean towel, or a foam board. Pin outside the stitched area, into the margin, working from the middle of each side outwards and alternating sides so the tension stays even. Check the grain of the fabric rather than the edges of the design: it is the weave you are straightening.

• Lacing beats glue, and beats tape — The traditional method is to stretch the fabric over acid-free board and lace the excess across the back with strong thread, top to bottom then side to side. It holds tension, it is reversible, and it does not put an adhesive in contact with the work. Self-adhesive mount board is quick and it is a decision you cannot take back.
• Why framed embroidery goes slack later — Fabric responds to humidity, and a piece mounted tight in a dry winter room will sag in summer. Lacing can be tightened; glue cannot. This is the practical argument for the slower method rather than a purist one.
• Glass or no glass — Glass protects from dust and hands and flattens the texture, which is half of why a piece looks good. Leaving it open shows the stitches properly and means the piece will need cleaning again. Neither is wrong; know which you are choosing.
• Keeping a hoop as the frame — Popular, cheap and fine — but the hoop keeps the fabric under permanent tension against a fixed edge, which is what caused the hoop mark in the first place. Bind the inner ring with cotton tape before final mounting and the mark is much reduced.

For storage rather than display: flat, in acid-free tissue, out of light. Folded pieces develop creases along the folds that a wash and block will mostly but not entirely remove, and daylight fades thread quietly enough that you will not notice until you compare a piece with one that has been in a drawer.
