Rope burn
A friction injury caused by rope pulled quickly across skin, distinct from the pressure marks that rope leaves behind.
The ESINEM Shibari Classes course separates rope burn from rope marks, which people often confuse: a burn happens when rope runs across the skin fast enough to scrape it away or heat it through friction. Rope 365 adds that such a burn can swell and bleed. Both trace it to speed, and both treat slower pulling and keeping a running rope away from the skin as prevention; the course also names rope dragged while trapped under other wraps. The course also warns that loose ends can whip around when pulled fast, particularly near the face. On materials, the course finds natural fiber gentler on skin than synthetic rope, and Anatomie Studio says the 6 mm jute it uses tends not to burn skin.
