I love these books. I can no longer read well because of my vision but have them on audio cd's. I love them. Although youd don't have to go in order, you can get confused at some points because it mentions something from a previous book. However, most of the time, they also clarify it in the new book. I have almost all of them so far. I think I've only missed 1 or 2.
They make wonderful gifts for new quilters!
