Basically, you choose a color combo, and others make blocks for you in your color, while you use your stash to make them blocks in their colors. It's fun, and I've loved seeing the creativity of the others in the group!
See what came in my mailbox?
And this pretty little thing in the bottom right . . .
And this one should arrive soon... plus two more! I see a modern sampler quilt in my future. :)
If you join the 4x5 Flickr group, you can see what it's all about. If you sign up this quarter, you have until January 15th to choose fabrics and send your blocks! Piece of cake.
