I love using up scraps leftover from previous quilts. I had all kinds and sizes of triangles leftover from the last quilt top I made. I actually pondered for awhile before I decided how to use them. I also had a lot of two different blues to use for the background fabric.
For the quilt back I used two leftover patchwork squares, I couldn't use for the quilt top, and cut some blue squares. I had 2 yards of Kona Tan in my stash that worked great for the back. The quilt will measure 54x55 inches after it's quilted.
