There are 21 of us in an ATW swap in one of my Yahoo groups.
I send one fat quarter to everyone who signed up. And they all send one fat quarter to me (and everyone else).
Then each person makes a block for each person using their own fabric and sends it back.
I have received almost (if not all) of my 20 blocks back. And they look gorgeous (pictures coming soon!).
The block I chose to make for everyone is called 4 Corner Flowers. Pat sent me the floral print, I added the green and white from my stash. And finished! My 4 Corner Flower is mailed back to Pat. And, of course, a handmade card tucked into the envelope too!
