Bowline

Sorry I pinched your idea Fi, (Tied Up) but I couldn't come up with anything else. I think yours is better.

I think bowlines are probably the prettiest knot, and one that everyone should be able to tie because it forms a loop that won't tighten and you can untie it even after it's been loaded. It's the one where the rabbit comes out of the hole, round the tree and back down the hole.
