Why is my embroidery puckering? Causes and fixes

Is it puckering, or something else?

Puckering is fabric drawn in toward the stitches: small ripples, waves or dimples around a line or a fill that don't smooth out when you stroke them. Two things look like it and aren't.

• A crease or a hoop mark. A straight fold line, or a ring where the hoop sat. It has nothing to do with the stitches, and it presses out.
• Slack fabric. Linen relaxes in the hoop as you work, so it sags. It looks wavy until you re-tighten the hoop, then it's flat again.

The quick test: take the piece out of the hoop and lay it flat on a table. If ripples stay gathered around the stitches, it's puckering, and the stitches are pulling on the fabric.

Find the cause by when and where it shows

Where the puckers sit, and when they showed up, usually points straight at the cause.

Fixes while you're still stitching

The hoop keeps going slack.

Bind the inner ring with cotton twill tape so the linen has something to grip, and tighten in small rounds, easing the fabric evenly all the way around. Don't tug one side: it pulls the weave out of square. The full method is in hoop sizes and hooping.

I can't tell whether I'm pulling too tight.

Look at a stitch from the side. A good one sits on the surface and the holes at each end stay round. If the linen dips toward the stitch, or the holes stretch into little slits, you're pulling too hard. Pull until the thread lies flat, then stop.

A fill is drawing the linen in.

Satin stitches all pull the same way, so a tight fill gathers the fabric like a tiny drawstring. Unpick it from the back and lay the stitches again, side by side, with no pull at all.

The gap between two fur strokes has closed up.

Unpick the tightest stroke from the back and stitch it again, looser. One relaxed stitch often lets the whole patch settle.

My stitches lean or wander as well as pucker.

That's the scoop. Needle 'n Thread rarely sees puckers when the fabric is drum-tight and every stitch is stabbed: one motion down, one motion up.

How to press puckers out of finished work

Rinse any stick and stitch sheet away first. The sheet must never go under an iron, and the rinse often relaxes mild puckers on its own.

1. Take it out of the hoop. Pressing works on the whole piece, not just the part inside the ring.
2. Make it evenly damp. If it's fresh from the rinse, it already is. If it's dry, mist the back with a spray bottle until the stitched area is damp all over, not soaked in one spot.
3. Ease it flat by hand. Lay it face up on a towel. With your fingertips, smooth the linen outward from the stitches, and straighten the grain so the threads run straight up and down.
4. Press face down on towels. Fold 2 or 3 towels on the ironing board, lay the piece face down, and press on the cotton or linen setting. Set the iron down, lift it, move it. Sliding drags the puckers along.
5. Block it if it still ripples. While it's still damp, pin it flat onto a towel-covered board with rustproof pins, grain straight, and leave it until it's completely dry.
6. Check it in the hoop. Re-hoop it loosely and look across the surface under a lamp. Ripples that remain around a few stitches mean those stitches are too tight.

When pressing won't fix it

A press relaxes the fabric. It can't lengthen a stitch. If deep gathers come back around the same few stitches after every press, the thread is shorter than the space it spans, and the only fix is to make it longer.

• Unpick only the tight ones. Lift them out from the back with the needle's tip. How to fix embroidery mistakes shows how to do it without hurting the linen.
• Re-hoop drum-tight before you restitch. Stitching into relaxed fabric makes the new stitches too long.
• Redo a whole fill, not half of it. A satin eye that's half tight and half loose looks worse than either.
• Know when to stop. Prop the hoop across the room and squint. A ripple you can only find from two inches away can stay.

Stretchy or thin fabric

T-shirt knits stretch every time the needle pulls, and very thin cotton has too little body to hold a line of stitches flat. Both pucker even when you do everything right. If you want to stitch on them, back the area with a stabilizer made for that fabric, so the stitches have something firm to sit in.

For a first portrait, the easy answer is a firm, even-weave fabric like pre-washed linen. Linen vs cotton explains why it's so forgiving.

A no-pucker checklist for your next hoop

• Pre-wash the linen. Needle 'n Thread has yet to meet a linen without real shrinkage; one test piece shrank almost half an inch each way. Wash, dry and press it before you start, and it can't shrink around your stitches later.
• Drum-tight, every sitting. Tap it before you start, and re-tighten when it sounds dull.
• Stab, don't scoop. Straight down, straight up, one motion at a time.
• Snug, not tight. Stop pulling when the thread lies flat.
• Short lengths. About 18 inches. A long thread drags through the fabric on every pull.
• No jumps across bare linen. Travel under stitches you've made, or tie off and start again.
• Small satin fills, started in the middle. Big shapes pull harder.
• Unhoop between sessions. The fabric rests, and you avoid hoop marks too.
