This is my first year as a prom sponsor (but I've decorated for many a Homecoming Dance). I'm trying to problem solve how to make (cheaply) a dozen large (I'm thinking 5' by 3') stained glass windows. Does anyone know if painting on plastic sheeting is doable? Can a clear shower curtain be painted? I think it would be easy to use a black narrow tape to create the outlines, and then fill in the areas with different colored paints. But, I'm not sure of the surface to use. We can have lighting behind to illuminate the "window."
