Hi there, I have been trying to help a customer repair a garden ornament. It is a gaudy, awful thing and I think my opinion of it may be causing my brain to not function well. I have tried several different ways to cut the mirror shape but I keep getting a run through the middle. The shape is similar to a stylized fleur de lis,if I were better at computers I'd send a picture, but I'm not. Help? Thanks. Melinda
