I haven't made the Bali Double Wedding Ring, but a friend did, and I believe it was all paper pieced. You probably could achieve a similar look by appliquing the star shapes, but it sounds like a lot of extra work to me (but then, I don't do a lot of applique). The best way to find out would be to create a couple of rings using your templates and then adding the star shapes. If you like the way it turns out, great!
