Your quilt is beautiful and I know he will LOVE it!
I made 3 D9P's for my boys last year for Christmas. My 7 year old (now 8) received on with Lightening McQueen, a gold, and that same checkerboard fabric. When I was tie tacking it and later on when I took the pictures those checkerboard pieces moved all over. Even when the I had the quilt lying perfectly straight it looked like they were moving. That is some really odd fabric!
