I made a gauze wrap last summer. The fabric was a cotton gauze, not necessarily as light as the bandage stuff. I got a length of gauze and actually didn't cut it at all. I folded it in half so that it was half it's width doubled over itself. I then ran it through my machine, sealing the open edge together. I left a part undone, turned it rightside out, and stitched the opening closed. I like that better, becuase the gauze was so lightweight, it isn't as comfortable so thin. It added strength and comfort being two layers thick and also solved the problem of the fabric being too wide. Only thing I wish I had done was get another yard, because I dried it w/o thinking and it shrunk.
