I have a project coming up where I'll use these blocks (taken from the book "Flower Festival" by Kim Schaefer) but I can't tell any more about it. . . I need to keep my quilting groups guessing!
Wool is expensive and not so easy to find but I urge you to try it sometime. I've had good luck finding small pieces of wool (5" x 7" or so) at quilt show venders' booths pretty cheaply.
Don't forget to take a look at the rest of Judy's Design Wall Monday participants.
