I had a customer with original art on thin paper, who wanted the art to float 1/4" off the surface of a mat. So I cut 1" x 1" pieces of white foam core and attached them to the back of the art paper and then attached the art (and the mounting points) to the mat board. I use white 1" framers tape to attach the paper to the foam core, but I am wondering if there is a better way. The art wasn't expensive, it was for a movie set, but it was an original. I rolled the framers tape when I attached it.
