I just bought a Judy Martin book and it is wonderful - There are 3 different patterns in there I can't wait to do!
The key - accuracy!!! She is very thorough even w/ which direction to press the seams.
I also have to 2nd the taking a picture of your layout. I'm working on this quilt and I'm not seeing what I'm wanting to - but in a picture, I can see. Yeah for me!
