my then-boyfriend wanted a blue quilt. I used many many blues and paper-pieced 6" snail trail blocks in light/dark so the overall design was a great tesselation. wish I had a pic to show you. I also had done a smaller of the same pattern in purples for my daughter's school auction in the 6th grade. I used muslin for the foundation and had each child make a block for an overall tesselation, which they had also studied in 5th grade math, so they got the concept
