I know this is an old thread but i am struggling with my stringer control and dot placement and this is BRILLIANT!! I am putting tape around another dowel rod to simulate the curvature of a bead, because i REALLY struggle getting my angles right when i am concentrating on being 'accurate' with my stringer. Definitely something i can do when i am off torch and watching my son, and i am sure somehow it will make me smarter too. Somehow.... I mean, these sorts of things always do, right???
