How to mend a hole in a knitted school jumper with embroidery thread

Repair a small hole at the back neckline of a knitted jumper so it stays closed and stops spreading. You will cover the gap with satin stitch, lock it with crossing stitches, then join both sides with backstitch. It suits beginners who can thread a needle and sew a basic straight stitch.

Steps

  1. Turn the jumper inside out and find the hole at the back neckline where the sleeve seam meets the body.

  2. Place the damaged area in a small hoop or hold it flat so the fabric does not pucker while you sew.

  3. Thread the needle with embroidery thread and knot the end. Work satin stitches straight across the gap, side by side, until the hole is fully covered.

  4. Sew a row of small stitches perpendicular to the satin stitches, passing over and under them, to add strength.

  5. Repeat the satin stitch and crossing stitches on the other side of the neckline if the damage runs along both edges.

  6. Sew backstitch along the neckline to join the two repaired areas and hold the seam in place.

  7. Check the outside of the jumper. Adjust any stitches that look uneven so the repair reads as a neat decorative line.

  8. Knot the thread on the inside, trim the ends, and press the area gently under a cloth.

Tips and common mistakes

Match the embroidery thread to the jumper colour so the repair blends in, or pick a contrast colour to make it a feature.

Keep the stitches loose enough that the knit can still stretch, or the repair will pull and pucker.

Do not pull the thread tight at the end, as this can gather the fabric around the hole.

Wash the jumper inside out on a gentle cycle after the repair to protect the stitching.

Questions

Can I use normal sewing thread instead of embroidery thread?

Yes, but embroidery thread is thicker and covers the hole faster. Use two strands of normal thread if that is all you have.

Will the repair be visible?

It can be. The backstitch across the neckline is meant to look like a deliberate decorative line, so choose a thread colour you are happy to show.

Does this work on other knitted clothes?

Yes. The same satin stitch and backstitch method works on any knit where a hole appears in an area that gets stretched, such as cuffs and shoulders.
