I'm preparing for a show later this month and discoverd that the top of my frames tilt downward (more than usual) when on the wall. I'm using wooden frames (20 x 24) that I made myself, and attach the wire about 1/3 of the way down the vertical orientation. The support chains at the gallery come out about 1/2" to 3/4" from the wall. I think this is aggravating the problem. I'm just wondering if the obvious solution is to attach the wire further up on the back of the frame, or if there are more clever ones??
