“Boom” is short for boomerang as in a boomerang swap. We just completed the 23rd boom swap here on the board. It’s a swap where 20 quilters send out fat 1/8ths of their fabric to each other and make blocks for each other. Janice is the fearless leader and does an outstanding job of coordinating. You can find the most recent swap thread under the swap section of the board. I just got my boom quilt back from the LA today so will post a picture when hubby gets home so you can all see what amazingly talented ladies the boomers are...
