What? Run out of Fabric!

Yes, it is true, I ran out of fabric. I am working on a block swap to be exchanged at a quilt retreat in a couple of weeks. We are swapping Kona black and a determined Batik Color. (We drew for colors using Crayolas!) My color is vivid tangerine. We are making 12 4-inch blocks for each person and swapping out with 18 people. Guess what???? I have 16 sets completed and I ran out of fabric. Not to worry--thanks to the good ole WWW. I just placed an order for more fabric so I should be able to complete the blocks by retreat time. Whew! I almost went into a panic!
