I love it, that's some pretty thick hemp too. The stuff I use is a lot thinner. They have a lot of instructions here http://www.knotingwork.com/Pages/knots.html Thats basically where I learned everything from. It teaches you how to do stuff other than half and square knots, too. They make it a lot easier for you to come up with original designs.
Hm, it looks pretty thick in the picture at least. Then again it just may be that you have better camera quality than me. I usually use really thin hemp since I have a thing for glass lampwork beads, and its hard for me to find big ones.
