I've been lurking here and admiring all the great blocks you've been sending and receiving! I hope to be joining you as soon as I'm caught up with current commitments. Great work, ladies. I also have been thinking about how to keep track of who sends which blocks. The photo and file idea is a great one. I have also found that it is hard for me to keep up with that system with the boomerang block swap...esp when doing 2 groups. So now, I keep a strip (scrap) of white fabric near the door along with marker and small safety pins. As soon as I bring the block in I write the name, swap and date I receive the block, cut it off and pin it with safety pin to the block. Then I can take photo later and not worry about just who sent it! I know it helps me. Hope to be signing up before long! Connie aka Chigger.
