How to sew a ripped seam by hand

You need almost nothing to fix a torn seam. A needle, some thread that matches your fabric colour, a pair of scissors, and a straight pin or two to hold things in place.

Choosing the right thread

Match the thread colour as closely as you can: hold the spool against the fabric in natural light. For denim or thick cotton, use all-purpose polyester thread. For delicate fabrics like silk or linen, go for a finer thread weight so it doesn't pucker.

Turn the garment inside out so you're working from the wrong side. Press the torn edges together with your fingers and use a pin to hold them aligned. This stops the fabric shifting while you sew.

Threading the needle

Cut about 45 cm of thread: long enough to work comfortably, short enough not to tangle. Thread it through the needle eye, pull it through until both ends are roughly equal, then tie a small double knot at the end.

Finding your start point

Begin about 1 cm before the tear, where the original stitching is still intact. Starting inside solid stitching anchors your repair and stops it unravelling again under stress.

Use a backstitch: it's the strongest hand stitch and mimics a machine stitch closely. Push the needle up through both layers of fabric, then back down about 3 mm behind where it came up. Bring it up again 3 mm ahead of the first entry point. Repeat.

Keeping even tension

Pull each stitch snug but not tight. Over-pulling causes puckering; too loose and the seam gaps under movement. Aim for the same tension the original seam had. Look at the intact stitching nearby as a guide.

Finishing the repair

Sew 1 cm past the end of the tear, into solid original stitching. To finish, make two or three small stitches on the spot: push the needle through the loop before pulling tight on the last one to create a locking knot. Trim the thread close.

Turn the garment right side out and press the repaired seam with an iron on the appropriate heat setting. Heat relaxes the fibres and helps the new stitches bed in, making the repair nearly invisible.

When to reinforce further

If the fabric around the tear is fraying or thin, run a second row of backstitches 2–3 mm from the first. On high-stress seams like trouser crotches or underarms, a whip stitch along the raw edge prevents future fraying.
