"But you only get back one that you sent"
Mom-6 - - - no one is getting any of their own blocks back. Everyone will be getting swapped blocks. If you want a block of your for yourself, you'll need to make an additional block for yourself.
Wildyard - while I understand tight finances, I maintain that this is a more cost effective way to get a scrappy quilt. Imagine how much fabric you'd have to buy to get a really scrappy quilt like this?? And the camaraderie we all build as quilt buddies. You could compare it to guys trading baseball cards. Of course, I certainly don't want to start any arguments between you and your husband. ((I'll be quiet now)).
