Chessboard Quilt

My son came home from college one summer and asked if I could make him a Chessboard. I've been making quilts for years, and I prefer strip piecing, so making him a Chessboard would be pretty simple.

So I made him a quilted chessboard. Then another, and another. In the end, I made forty. Like any good quilter, I kept all the leftover bits. What does a quiltmaker make with leftovers? Another quilt.

I knew I wanted to do something interesting with them, so I decided to make a block in the shape of a long rectangle.I liked the fact that the blocks could be arranged differently.
I sewed about 2/3 of the blocks I needed, with equal amounts of left and right blocks.
Then I started arranging the blocks. At this point, I was able to determine just what I needed, for example, a left leaning block with a wide light strip at the top...
This is the finished quilt.
