Blind stitch

A stitch that catches only a few threads of the outer fabric, so the thread is almost invisible from the right side. It is used where a seam or hem should not be seen — jacket hems, linings, trouser cuffs — and it gives a cleaner, more tailored finish than a visible topstitch. It is weaker than a through-stitched hem, which is why it appears on tailored garments rather than workwear. On a spec sheet a blind-stitched hem signals a dressier garment; it is not a durability feature.
