OK...just finished a trying hour and thought there must be some collective wisdom on this.
I'm building the frame for a mirror. So i figured it would be a good idea to mount the frame to the wall first before i got the glass installed. I bought a hanger that has to be mounted "just right" -- keyhole hangers (http://www.homedepot.com/p/OOK-20-lb...0236/100018911). Maybe i picked the wrong type of hanger but i'm curious if there's a good method to get everything lined up.
here's what i did. I put the screws in the studs first and then pressed the frame against those screws to see where the screw heads hit the frame. In theory this should have worked fine but it still took me a bunch of trial and error. Is this the typical method?
