Thanks Charley, Almost done with the cutting and looking forward to doing some experimenting. Will sanding in those exposed areas work? Most Led strips are 1/4" wide and I cut the plaque 12" wide because there are some strips available that size. Can I double up the Plexi Glas (typically 1/8") or look for wider material? Should I back up with 1/8" BB or just apply a dark or reflective coating for best effect? Lots of questions, just have to start experimenting until I find a "light bulb" like Edison, that works. Ah!, tungsten, Who would have thunk!
