There's a book about knots by Klutz that was featured here. Comes with string(s) attached.

I don't remember too many knots, but anything that stuck was learned from that book. Amazing product: subject, content, presentation and quality construction!

My only complaint: I remember it was hard to make it fit on my bookshelf :)

I'm not a frayed knot.
