PS!!!
Rayna Gillman's book is well worth reading:

I also found the books by Jean Wells a total inspiration, enough that I also took a class from her. She was an amazing teacher, and she has several interesting videos up on YouTube.

I also really enjoyed the wonderful book by Nicholas Ball!

I have also learned a TON from copying old quilts (I love copying antique baby quilts) and wow...copying the Gees Bend quilts. Everyone should try to replicate a few of those!
