In the past I have used sandpaper to lightly "frost" clear plastic, which works fine on small pieces.
Recently I found some larger blocks of clear acrylic so I am finally able to scratch build some props with larger "frosted" areas. The problem is sanding it is not working, especially since I want to put a light behind it.
Can anyone suggest how to give the acrylic that "frosted" look?
Also, would having the frosted look spread the light more evenly?
With what I have right now I get very little, if any, light spread when I put a bulb behind the piece!
So you know I am building a wall communicator from the original Star Trek series. If you are familiar with it then you might recall that the emergency light appears frosted when off and flashes red when on.
Any help would be very much appreciated!
