One Block Wonders by Maxine Rosenthal. This is the book I used.
Thanks Jenell. She has 4 books out. There are so many on the market, it's nice to get a referral on which book to buy. I've ordered it, can't wait to start!
I love, love, love this quilt! It's one of my favorite patterns and I've made 3 of them. They are a lot of work, but well worth the effort. Yours turned out beautiful!
