Anyone recommend a glue/sticky stuff that will hold a 7" single and sleeve in place in a picture frame between glass and a glossy backing sheet. I'd like something that's non permanent and won't leave a stain or tear the surface when removed. I was thinking of something along the lines of a non staining Bluetak, or a gentle version of the gunge that's used to stick things like CDs to magazines.
Anyone know of such a substance?
