This is the number one best light diffusing material I've found. It spreads out a single point of light across a very large area. Use it for light walls or backings. It's the same material I use for my Carbonite Base kits. Perfect for deathstar wall panels or displays. I think it looks best with the frosted side facing outwards but it can be reversed if you want the surface to be shiny instead. You can hot glue it in place or affix it with other methods.
