I've made two more groups of 6, so I now have 144 108 blocks (I knew something in my math was off!)although I'm only showing 36. I should mention that this is inspired by the Crossroads quilt in the book Colorful Quilts for Fabric Lovers, but since I didn't feel like making 3 different types of blocks (changing where the middle strip falls), I'm actually following the pattern for City Tracks in the book City Quilts.
I'm going to link this with Patchwork Times' Design Wall Monday again. I think doing that gave me a lot of incentive to keep at this.
