Size spacer for pastels

That should work if you're glazing it with glass. If you want to use acrylic, you may not be able to space it enough no matter what you use.
 
I think the rule of thumb in preservation is a minimun of 1/8" from the surface of the art, so there is some adjustment for the thickness of the art. I tend to err on the side of caution and make shims 1/4".
