Hi, all. I am trying to brain storm ideas for Christmas lights on a cake that I am making that is in the shape of a restaurant. The customer wants to have Christmas lights around the edge of the roof and the roof hangs over about a centimeter.  I wondered if there was any way to add free hanging Christmas lights in an up/down motion to look like half moons. And if it's not possible, what about a plain string of lights flush with the edge of the roof. I don't really know what to do. I suppose I could just take little balls of fondant and stick them on, but is there any way to get a more realistic look? Thanks!

Royal icing stringwork would do the job. If you are not confident that they won't break in transit, just pipe along the edge of the overhanging roof and stick the fondant or coloured dragees on.

AOP do you mean actual battery powered lights or just decorations that look like lights?

Decoration, not real.

Dayti, that's perfect! Thank you!
