This started with the ‘Perspective Grid 1′ block from the EQ library. I then drew a simple block and merged the two. I also deleted the patch lines where the grid effect is broken by solid strips of color.
The notecard on the original block designates it to work in foundation or paper-piecing. With the alterations, it still is a good fpp candidate.
With all the piecing in the blocks, a simple border seems to work best.
