Thank you ladies. :)
Celeste, I think you have to have 7 different fabrics in one color from dark to light, and 7 of another contrasting color dark to light, and then the background fabric. I used all batiks except for the background.
The pattern was developed by a woman who works in one of our local quilt stores. She gave classes on this quilt and sold the pattern locally to the different quilt stores around the area. I'm not sure if the pattern is available anywhere else.
