I made a chocolate collar like I saw somewhere on here - for a cake I made. I melted the Wilton dark chocolate melts and spread it onto acetate sheet. Then when still quite pliable, I wrapped the cake with it. Once it was hard, I peeled the sheeting off. I have 2 questions:
1. Is there a good way to create a smooth seam where the two ends meet?
2. Is there something I can do to make the chocolate have a shiny finish? Mine had cloudy marks in it.

Thanks for any help. I'm doing this technique on a wedding cake for this Saturday.
