I just joined the Postage Stamp block swap on this board.

I think it will be great.
Up until now my system relies on careful scrutiny and considering my current mental abilities that system is doomed LOL.
I'm already exchanging blocks with some members, and I make sure I only cut enough to go around and one for me in the correct size.
Are you getting the postage stamp bug? It's going to take awhile, but I can't imagine a more interesting and memory filled quilt to make!
