besides the Farmer 30's wife here on the QB, there is also a group on Bloglovin that is doing a sew along but it doesn't look like they're doing it alphabetically as here on the QB. I purchased the book and have tried one or two blocks but since I'm new at PP, I'm going to practice with a few first. I also purchased Carol Doak's Craftsy class in hopes to improve my PP skills.
All the books I have seen contain approx. 100 blocks.
