Your into video games, and I'm sure there is a whole host of fantasy things, that would make a quilt or wallhanging. It's just use the key and unlock the door. How about going with something, that you could use beads and charms to create, on a wall hanging. Play with a new area of quilting, Challenge that imaganation, Make it work for ya.
