Can't help much but I will follow this thread, as I'm looking at Shar Jorgensens' templates
http://www.qheartland.com/pd_double_wedding_ring.cfm
Have tried the "Rings that Bind' method - and mucked it up. Didn't realize the end section should be cut on the bias, and my backing circles stretched (or shrunk) with sewing and ended up different sizes. So now plan on undoing it all and starting again, as I adore the fabrics.
Was also looking for the templaates for Judy Niemeyers' Bali Wedding Star, but couldn't find them on Creative Grids. Perhaps they only come with a kit. Will look elsewhere later
