I want to add some foam acoustic panels to a wooden (interior, roughly 30x80 in) door - they are roughly 12x12x2 inch squares, and quite light, to the point where I think double-sided tape would be enough to hold them in place - however, I would like the option of being able to relocate them at some point (door is likely to be replaced at some point in the future) and would like to stay away from glues/sticky stuff because those seem fragile enough to be destroyed if they were to be pulled off from something like that - Any ideas as to how to proceed?
I was thinking perhaps a wooden grid "frame" to hold them, where they would just be "stuffed" into the frame, like this:
and then mounting the frame similarly to how a large mirror would be mounted.
Any issues with doing it like this? any better ways?
