I know there is a specific name for the type of machine embroidery used by H Bar C in the 50s, and specifically on Nudie's garments. I can not for the life of me remember what it's called. I want to say "Corelli," but that isn't correct. Any help is greatly appreciated! Thanks, y'all.
Chainstitching? - a Frenchman named Antoine Bonnaz invented the Cornely machine in 1865: https://collection.maas.museum/object/370932
Probably you are thinking of chain-stitch, Leisa, though there are also fill stitches that resemble chenille and are called chenille stitching.
