The standard 5×7″ acrylic frames we offer are manufactured to hang on a wall. Patti designed an easel backing specifically to fit this popular frame so it can now sit on a flat surface like a desk or a shelf as well as still have the ability to hang on a wall. To install, simply twist the knobs to remove the glass, artwork and chipboard from the frame. Then pull the knobs out completely. Discard the chipboard and place the glass, artwork and now, this easel backing, into the frame. Push knobs back in (with top knob being hangable) and twist to close.
