What's the best support for hanging my large, heavy antique mirror? I want to hang it above my bedroom dresser. It's 5' wide and 3 1/2' high. The hanging loops on the back of the frame are in good condition. I understand that it's the best distribution of weight to hang it from those two loops, rather than running a wire and hanging from a single center point. But without hitting studs, I'm afraid to hang it by toggles in the drywall. Will that really be ok? Any other ideas? Thanks!
