Definition
A ladder stitch is a hand stitch that closes an opening between two folded edges invisibly, by alternating small stitches inside each fold and pulling them tight.
Many projects are sewn right sides together, turned right side out through a gap, and then the gap is closed by hand. The ladder stitch closes it without a visible seam: cushions and stuffed toys, bag linings, belts and ties, or the turning gap of a scrunchie.
How to sew it:
- Press both edges of the gap under along the seam line, so the folds meet.
- Knot the thread and bring the needle out from inside one fold.
- Cross straight over to the other fold and take a small stitch inside it, 3 to 5 mm (1/8 to 3/16 in) long, parallel to the edge.
- Cross straight back and take the next stitch in the first fold, starting directly opposite where the last one ended.
- After a few stitches, the threads look like the rungs of a ladder. Pull gently and they disappear as the folds close.
Keep the crossings perpendicular to the edges, since slanted crossings show. Finish with a knot hidden inside, pass the needle into the item and out a few centimeters away, then cut the thread close so the tail sinks in.
The ladder stitch is closely related to the slip stitch, and the two names are often swapped. It can also mend a split seam from the right side without unpicking anything. For a strong, visible hand stitch, see backstitch.
