Maryanna, thanks for the advice on glass shops. I found one near my office ("We Fix Your Panes") that cut glass to size quickly and for a reasonable price. I brought it home tonight, and it's a thing of beauty. It brings a tear to my eye. ;-) It's much thicker than I expected, although that's one thing they didn't ask me on the phone when I ordered it. I had painted my plexiglass palette gray on the back, but I think I'll hold off on that for this. It's too pretty. But I can't wait to smear paint all over it this weekend!
