I want to frame pictures that will be measuring from 3 to 8 feet in width and about 7.5 to 20 inches in height. I understand that the picture cannot come and stay in contact with the glass and that’s the problem. With smaller pictures, the use of matting takes care of this. But, with larger images such as I’m dealing with here, how do you keep the picture away from the glass. Matting just doesn’t, that I’ve found anyway, come this large and would be extremely wasteful anyway.
