My son was in to "Dungeons and Dragons" when he was in high school. I had him pick out a batik panel of a dragon and used it as the center. I surrounded it with drunkard's path in the colors that were in the batik panel. He loved it. I also made sure there was a lot of red and black, as those were his favorite colors. Seems a lot of guys like red and black.. (and blue, too) You might take him to the fabric store and let him pick out what he likes.
