I have been tangling for several months and have been collecting patterns from art books. I am delighted with this collection. It is well worth the nominal cost. You would have to purchase a lot of books to get this collection. My only complaint is that a few of the instructions for patterns (i.e., "intersect") are incorrect or incomplete. But this is only a minor complaint.
