I've seen some people poke holes through their coroplast to put minis, or LED's.
I've seen people place plastic rectangles, or metal squares behind the coroplast to illuminate it.
Has anyone done both? they didn't have to be on at the same time, just wondering if anyone's tried it?
I was thinking a star, or candy cane, then if some instances, you could outline the object for one kind of look, and then at some other time, you could just illuminate from behind to get a different kind of look.
thoughts?
