I tried the 10 minute blocks without the book. When I made like 14 blocks I knew I had to have the book. When it came I got carried away and made like 30 of the things!! I made them with black and white blocks with floral inside block. It rarely took over 8-9 minutes to complete one block once you get the hang of it. Good luck to all that gives it a try, I think you'll be happy with them.
