I have done several BOMs, mostly the ones where the shop provides the fabric and instructions each month and I get to keep them. I also enjoy the BOM at a LQS where the shop gives us a small 7 inch square of fabric, we all add our own to make a 12 in block and turn them in. Then there is a drawing and one person gets to take the whole shebang. It is fun to win and fun to share! Either way I am happy to join in.
