HINGING PAPER ART
Pocket corners and mounting strips may be used separately or in combinations to hold artwork against the back support. It is important to allow some room for movement, or buckling will occur with changes in humidity.
Pocket corners and mounting strips are available in art supply stores, photography suppliers, or craft supply stores.
Mounting corners and mounting strips are good choices, because they make no adhesive contact at all with the art, but be sure they are made from non-acidic materials like acid-free paper or polyester material such as Mylar®.
