What a cute dotty quilt! I've found that dots can be great mixers, not solid but not quite a defined "print", either. I use them when I need some backgrounds or extras for kids' fabrics. They work so much better than solids.
I collect moderns-- Amy Butler Soul Blossoms right now, and also have a small collection of "Taza" by Westminster. I collect 30's reproductions and batiks, as well.
