I think "Awash With Color" by Judy Turner is the best one out there.
(there was on sale her on the board this morning but someone, smartly, snatched it up.)

Grab one of the used ones. Pretty cheap.
It had been oop for a few years and then they reprinted it again.
There is also Reversible Quilts by Sharon Pederson.
Slightly different method.
