At Materpiece Framing we mount according to the artwork in ways that are appropriate and best for the art.
Works of fine art on Paper
All methods of attaching the fine artwork to the backing board (mounting) must be reversible without harming the artwork. The attachment should also be less strong than the paper of the artwork -- this allows the attachment to give before the paper of the artwork tears or is damaged. Archival corner pockets may by used on many types of artwork, others will need linen hinges, or mulberry paper hinges and wheat starch glues.
Special mounting issues.
