| Lovely scale work you are doing there.
When I used to do windows, rather than acetate, I would go to a good photographic shop and order a box of glass slide mounting frames. I would get the ones for 2 1/4" square format. After stipping them down carefully, you would get two perfect pieces of real glass, about 2 1/2" square out of each mount, and it was about 0.025" thick. Easy to cut with a carbide scriber and tough as old boots. It doesn't discolour with age, and doesn't scratch when cleaning.
