I've read "Free-Motion Quilting with Angela Waters" and I thought it was very good. Also "Mastering Quilt Marking" by Pepper Cory.
I am hoping that there will be some nice modern title suggestions that show up here. At Quilt Odyssey and also Quilt Extravaganza there was a book booth (I'll have to look up the name) which was all quilting and sewing. There were a ton of modern quilting titles and they all looked really good. I wish that I had jotted some of the books that I liked down. This is something we should keep in mind for next year.
