I learned a really cool trick a few years ago, but can't remember where, or who posted it, but if you mix water and a little Elmer's (white school glue) together, then pain it on a clear surface, glass or plexiglass, and it really works well as a frosted glass effect. It remains translucent enough to let light shine through. Here's a lantern I purchased for $7 in he camping department at Walmart. It was gloss black with clear glass when I got it, so I did some faux paint, and used the glue trick on the glass. I shot a little flat back spray pain on the inside top to give the glass the bit of a burnt look. I love the glue trick. Cheap and easy!
