I've participated in a number of the swaps here for Postage stamps. (It's the easiest since I don't have to buy fabric!) I've got a large enough selection that I think I will just put them all in a large grocery sack, shake to mix them up a bit and then start sewing! I've decided to use a neutral like a white or black every X number of blocks. I think it will be fun but is going to have to be on the quilt back burner til all the others have had their turn in line! Like most people, I have far more projects than time! :) Oh and I have duplicates as well and think that it would be fun to spend time looking for them! It would keep my grandkids busy!
