I am building a feaux stained glass motif for a project, and have run into a snag in my pre-planning. I am using colored acryllic plastic sheets for the glass itself and frosting the facing side using the wet-sand technique to help diffuse the light coming from the back side, but I realized that I don't have any idea what to use for the joining. I need something that I can join all the pieces with the way you would use lead in a traditional stained glass project, that is black, opaque, and wont cause the plastic around it to melt.
Thanks.
