I've done two BOM and won't do another one. You start out with a $1 per month, (at my LQS) if you get your block at the specified time. The boarders and the backing really adds up. Plus if one of the blocks is cut wrong, and that did happen to me, it causes problems if you don't do the block as soon as you get it. I like to prewash all my fabic and I would be a little afarid to wash the tiny pieces. I've seen the wool BOM quilts in one of the quilting magazines and it was about $500.
