Why embroidery puckers, and how to stop it

Puckering is fabric that has been pulled in by the stitching and has nowhere to go. It shows as ripples around the design, usually worse on the sides than the top and bottom, and it is nearly always the sum of several small mistakes rather than one big one.

Work through it in this order

  1. Density. Loosen by 0.05 mm and re-sew. Too much thread in an area is the most common single cause, and it is the cheapest thing to test.
  2. Underlay. Add it, or move up a type. Fabric that is not fastened to the backing before the top stitching goes on will be dragged by it.
  3. Stabiliser. Move to a heavier cut-away. On knits this and density together account for most puckering.
  4. Hooping. Hoop the fabric and stabiliser together, firmly but not stretched. A drum-tight hoop hides puckering until the piece is released.
  5. Design size and direction. A very large solid fill in one direction pulls hard along that axis. Splitting it, or turning the angle, spreads the load.

Can it be fixed afterwards?

Partly. Press from the back over a towel and let the piece cool flat; light puckering will relax. Fabric that has genuinely been pulled out of shape by an over-dense design will not fully recover, which is why a test sew on a scrap costs less than a ruined garment.

Common questions

How do I stop embroidery from puckering?

Work through it in order: loosen the density by 0.05 mm, add or increase underlay, move to a heavier cut-away stabiliser, and hoop the fabric and stabiliser together rather than floating the fabric. Density and stabiliser between them account for most puckering.

Can puckering be fixed after sewing?

Partly. Pressing from the back over a towel and letting the piece cool flat helps light puckering. Fabric that has been pulled out of shape by an over-dense design will not fully recover, which is why a test sew is cheaper than a ruined garment.
