I was able to talk to a knowledgeable person who helped me select just what I needed. Also, years I'd called to order nylon tubing to web a canoe seat and the person I talked to set me straight and said to use some kind of (can't remember) Poly because nylon stretches too much. Now, years later, all of the YOUTUBE instruction I found online were no good whatsoever.
