In a nutshell, it is a book of 120 tangles with stepout directions and a spinner tool that will select one random tangle each spin.
After exploring the tangles in the book and practicing the basic steps, challenge yourself to put your own "spin" on them. Make your art your own! If you run across a tangle pattern that just doesn't suit you (it does happen), mark it out on the spinner. Use post-it flags to mark the pages of your favorite tangle patterns, or highlight your favorites in the visual tangle pattern directory in the the index.
Look for Tangle Time sometime in the next couple of months!
