I am experimenting with mounting works on paper directly onto a cradled board, since I'm not a frame person. Seems to be working well. This is a new piece, 18 inches square. I applied a layer of Utrecht gel medium onto the panel's surface, pressed the paper onto it, put down a clean sheet of paper and rolled a brayer over it, put it in front of a fan, and trimmed the edges against the sides once the piece was dry. Neat, easy, and no glass between the viewer and the work.
