I used the Eleanor Burns book and mine turned out nice. One thing is very important: press your seams correctly. If you don't, you'll have a fabric fight on your hands. If you do, the pieces will interlock and you'll have a nice quilt. I did a double and am planning a triple. We aware also that as you add chains they get bigger faster.
Did you get a load of this one yet? Yikes:
