I have done a lot of Judy Niemeyer quilts, both big and small and I am currently working on Brilliant Beauties of Joy by Jackie de Jonge. I think there are pros and cons to both but I prefer Judy's patterns. The big con for Judy's patterns is the tremendous amount of fabric they require and Jackie's doesn't seem to be as much a fabric hog. Judy's instructions are easier to follow, and once you've learned to read her patterns you can do any of them. I watched a video class with Jackie on The Quilt Show before I started and I'm not sure I could have gotten as far as I have if I hadn't watched it.
