I have joined another swap. This one is called The Four Seasons Quilt Swap Summer Block Swap.
Boy that was a mouthful. You will make a total of 40 blocks (20 mailed before July 15, and the other 20 by August 15.) You pick whatever color you want and what you will get back is an assortment of colors. The block seems easy enough for anyone to make correctly, so it should make a happy type quilt.
