stripey rainbow quilt

I've squared up my stripey blocks to 13.25" and I've assembled all the blocks I've got left from the first two sets of 2.5" precut strips. I think I like it, but I've only got 15 blocks, and I think I want 30 (for a 5x6 layout). I'm in the mood for large, colorful quilts to curl up under during these dark, dreary winter days.
