A while back, I made a rope hammock.
People in general seem to think that this is pretty neat, and some even want to know how to make their own!
For them, I've decided to write a tutorial. You'll find that here.
If you've ever made one of those para-cord survival bracelets, the net of the hammock is the same knot.
There are a few other ways to tie it, this is just the easiest to draw.
