I generally like block of the months. I've done several ranging from free on the internet with your own fabric to $30 dollar a month BOMs. There was one I ended up hating and still haven't finished the blocks. One of my friends talked me into doing the Saturday Sampler with her. It was one of the pay 5 bucks the first month and if you bring back the completed block you get the next one free. I think I only did maybe three of the blocks and just paid for the rest of them. It was done with templates and I really hate templates.
Right now I'm working on two BOMs. One is Vintage Valentine and the other one is Christmas Traditions from the book "Four Seasons at Minglewood".
I'm going to be working through UFOs the next few months so I might get to that Saturday Sampler quilt.
