It's by Gai Perry -- love her name! Anyway, one of the projects is to cut up two inch squares, put them in a bag, and then pull them out at random and lay them out. You are allowed a couple of switches if some color placements bother you, but if you are tempted to move too many, you put them all back in the bag and start over.
It was a really good exercise for me. I learned that I am not cut out for true scrappy (no pun intended). I prefer controlled scrappy. But I did enjoy seeing what new possibilities could come up from scrappiness.
I highly recommend that book.
