I have 13 pieced (I only need 12 for my quilt, but it's always a good idea to have a spare. I'll probably make a pillow.), and since I need a roadtrip project, I will hand-appliqué the blocks onto my white Kona cotton background fabric.
I also pieced two "Perfect 10" by Swirly Girls Designs quilts in very different color ways. The bright one is another of Pat Sloan's fabric lines "Bobbins & Bits" and was featured on her blog this week... http://blog.patsloan.com/2014/03/pat-sloan-quilts-by-you.html ...and it's not even quilted yet!
I have already quilted the brown one, and named it "Perfectly Feathered" after quilting it with Fantasy Feathers from itsaquiltthing.com.
