Question: what is the difference between s-lon and c-lon cord?
Answer: The product is made at the same factory, on the same equipment, and to the same specifications; the only difference is that C-Lon is a taller spool than S-Lon/Superlon and C-Lon has more yardage on each spool. Other uses for this material are in upholstery and fabric trims like top-stitching on shoes and purses.
