Here is a link on how to tie it. The first section is the one i am describing, and the strongest.

Or, if you have something to attach to it that can open, use a bight and tie a figure-8 knot. Same knot, easier to tie. Oh, and put an overhand in the free end, preferably around the standing part. That way, it'll cut or wear before it comes out.
