Every year I make small quilts for children 6-18yo. It is always hard to make something for an older boy. I just found some great outer space fabric I am going to use for borders and maybe the center of stars. I made a Tardis quilt for a teen girl at her request and it was a BIG hit with her friends. I also lean to earth colors for older boys and animal prints. Wildlife and dogs and cats Good luck. It is so nice of you to make a quit for these boys
