I like the jewel box pattern to showcase fabrics, and I think it would be perfect for these. You'd need a 'quiet' background fabric to tie it all together, maybe tone on tone gold or green so the mostly white fabric would show as well as the red.
Here's some links for jewel box patterns:
Jewel Box from About.com
Jewel Box from Jinny Beyer
Jewel Box from Quilter's Cache
I just finished a jewel box quilt (binding it now) and I did each small block in the same fabric (two 4 patches and two half-square triangles) It looks great and really shows off the fabric.
