How to hang a big mirror?
So we have this 3ft wide by 2ft tall mirror that weighs 25 to 30 lbs. It has two triangular hoop connections on the back. I was thinking of getting some heavy wire from a framing or arts/craft store, attaching the wire to the hoops, screwing some hooks into the wall studs with wood screws, and hanging the wire on the wall hooks. BUT, the mirror specifically says not to use a wire to hang it. The only other option is to screw two hooks into the drywall using drywall screws that line up with the two hoops on the back of the mirror, but I hate trusting dry-wall screws.
Why do you think it says I can't just use a wire with wood screws into the studs? What should I do?
