Pulling your own stringers will undoubtedly make the act of decorating the skulls easire when it comes time to do so. Youll be able to choose your own widths and colors. Also a hell of a lot cheaper. Youll also screw up alot less stringers ( and skulls ) if you know how each color likes to be worked. All those hours spent pulling stringers will add to your skill base which is good because in glass cutting corners doesnt get you very far.
