I am a member at the QuiltingBoard.com and am participating in my second boomerang swap.
How does a boomerang block swap work? Each group member mails a fat eighth (F8) of fabric to the other members; you make a block using the received fabric (and whatever other fabric you add to it) and mail the finished block back. It's a fun way to get a large variety of blocks made - and no two ever look the same! My goal for this swap is to create each block with a design I've never used before.
There are many other swaps and discussion forums at the QuiltingBoard.com - join us!
