If you want a double mat, you won’t need spacers. Simply have a window cut in the top mat that is large enough to leave both the art’s raw edges and some of the bottom mat visible.

There are several ways to attach your art to the bottom mat:
o dry mount – this is an economical but irreversible process
o double-sided tape – tapes are available in both archival & non-archival
o spray adhesive – sprays are easy to use, but most often non-archival
o hinging tape – available in archival linen, used to make a v-hinge or h-hinge

Remember, when you frame original art or reproductions of value, only use adhesives advertised as “acid-free and archival”. Also, hinging tape should be weaker than the artwork so that, under stress, the tape tears instead of the art.

Lastly, don’t forget to check a frame’s rabbet depth before you buy. The “rabbet” is the recess or channel on a frame into which your artwork fits. Its depth should be greater than the thickness of your art, mat(s), acrylic and mounting board together. Every frame’s rabbet is listed on our website.
