Not sure if I will get to join you or not since I will be out of pocket a good deal the next few weeks. However in case I do get to do this, I want to be sure that it would be ok for each block in a set to be different fabrics from the others in the set. I think that's what you indicated, but I wanted to verify.
This looks like a lot of fun and a great way to use up those bits and pieces that are left over.
