I don't know how this would work with puzzle types outside of jigsaws or puzzle boxes, but is it okay to ask about the best way to preserve a puzzle? I assume I would need to be specific... for example that this:
How do I preserve a 3D jigsaw made of plastic?
is better than this:
How do I preserve a 3D puzzle?
But I'm wondering if the question itself is okay. When I was going to ask this initially, the title box had the "What is your creation and solving of puzzles question" text in there and I was skeptical about asking since my question has nothing to do with creation OR solving a puzzle.
