Is there a way to store finished panels or canvases in a type of box or bag? I don't really want to use shelves or anything that leaves the artwork out in the open. I was thinking of something like a wet panel box, but a wet panel box is meant for temporary storage and I wanted something like that, but permanent storage even after it dries. Maybe closed storage isn't good for the painting but I don't know nothing bout that.

I always left mine hanging on a wall. Of course you have to have some wall space.
