The mirror is finally done!
I think it came out amazing for having no idea what I was doing! I used Citristrip, cleaned it with mineral spirits, let it dry for a couple of days, then sanded it with an industrial strength scotch pad, used an attachment on the air compressor to blast the dust away, and stained it with Minwax Red Mahogany and finished with a coat of poly.
It's now ready for it's new home. It's going to go above the couch in the living room. That's really the only place where it'll look right because of it's size. It's about 4'x3'. I'll post pictures once it's been hung.
