And you're right that QNM doesn't print patterns of the it's cover quilts as they are usually master award winning quilts.
This quilt is gorgeous, and I think a bit more difficult than the vortex one. It's only got 32 curved sections, which could be easily paper pieced, but the color placement makes the quilt.
Can't really mess that up on the vortex quilt. ;-)
