What is the minimum number of stitches on each side when performing lock stitching?

Explanation:
Lock stitching finishes the seam so it won’t unravel under load. To secure the end of the stitch line, you need enough stitches on each side to lock the thread paths together. The minimum specified is three stitches on each side. This provides redundancy so the seam stays solid even if tension varies or a single stitch loosens, and it helps the needle and bobbin threads lock against one another. One or two stitches aren’t enough to hold under stress, whereas three give a reliable, durable termination. When finishing, backstitch or end with at least three stitches visible on each side to ensure a secure, long-lasting seam.
