Years ago I made twin quilts for two pre teen grandsons who loved skateboarding. It took me some time but I found several fabrics with different characters on skateboards and scooters. Mummies, frogs, turtles, flamingos, kids, etc. and made the quilts in the bricks and stepping stones pattern with bright colored sashing. The quilts turned out fantastic, the boys loved them. I can't find the pics of them right now, they must be still on the old hard drive. Another themed quilt I made for a teen was a card trick quilt made with 28 different animal prints. This was for a grand daughter who loved wild animal print fabric.

See, you can make just about any pattern you like into a themed quilt.
