Chain Stitch

Chain stitch builds a line of stitching from a single continuous thread looping through itself, one loop pulled through the next, which gives the stitch visible texture and stretch compared to a flat lockstitch. Old-school union-made tees and workwear used single-needle chain-stitch machines for hemming specifically because that stretch let the hem flex with the fabric.

Today chain stitch shows up in two places buyers actually care about: hems on reproduction and vintage-style blanks, where brands chasing that union-made look specifically spec a chain-stitch hem, and as a decorative embroidery technique for retro-look logos and lettering, done on dedicated chain-stitch machines rather than a standard multi-needle setup. The look reads instantly different from modern satin-stitch embroidery, looser and slightly textured, unmistakably old-school.

If a client asks for a vintage or letterman feel on a custom order, chain-stitch hemming or chain-stitch embroidery is the detail that actually delivers it; modern coverstitch hems and satin-stitch embroidery won't read the same way no matter how you style the rest of the garment.

One thing buyers don't expect: pull the wrong end of a chain-stitch line and the entire row can unravel in one continuous pull, since it's all one interlocking thread. That's a real risk on garments that get rough handling, part of why the technique mostly survives on decorative embroidery rather than structural seams today.
