I have a version of this pattern called Two of a Kind.
(The name comes from the fact that designer Rachel Shelburne did this pattern using a variety of batiks, and her mother Darlene Zimmerman did the same quilt in her signature 1930's retro prints.)
A lap size quilt can be made with 10 FQ's and just over a yard of a background material (before borders).
This is in American Patchwork & Quilting Magazine, April 2008.
