If you scratch a piece of glass, that's where it will break. Might try
masking off very fine lines and painting, then peeling off the tape.
But making real groundglass is pretty darn easy. If you have a lapidary
supply anywhere you can get a lifetime supply of 600 grit abrasive powder
for very little money. Just put a pinch between two pieces, mix with a
little water to make a thin paste and rub the two pieces together until you
have a nice even matte surface. Doesn't take long at all. They come out
very nice and bright and you can pencil or sharpie all the grid lines you
want on them. You can even make a cheap fresnel with one of those full page
magnifiers from an office supply house. You may laugh, but they're
definitely better than nothing in reduced light. You have to support the
magnifier well while you cut with a very fine tooth saw because they break
quite easily.
