I am getting to the point where things are pretty smooth when it comes to framing. I wanted to ask a couple questions, and share some tips I have learned. Questions first: Plexiglas or glass? I can cut either, but glass is certainly easier to keep clean (and static free). How does one add a "dust cover" to the back of a metal frame? I have no problem getting the paper cover drum tight on the back of a wooden frame, but don't know where to begin using metal frames (maybe it isn't necessary). OK - a couple of tips. If you have ever used plexiglas as a glazing, you know how the stuff attracts dirt when you peel off the protective cover. I peel off one side carefully, and then lay that side on top of my matted print. I then peel off the front, never separating the plastic from the print other than lifting an edge to reach a speck-o-dirt. This really cuts down on the specks I have to chase. Add two pieces of heatshrink tubing (about 1" lone) on the hangar wire before twisting the ends. Slide it over the sharp ends of the wire and shrink in place. This keeps the person hanging the print from drawing blood. Always print, mount, mat and frame one more than you think you will need (or maybe two if it is a photo of your daughter's soccer team).
