I've been Googling, but I haven't managed to really find something satisfactory on the subject. I'm at the point where I'd actually like to keep some of the paintings I make, at least for now, and I'm trying to find the best way to store them. Usually, they just get piled on top of each other with no care in the world. I know gouache can be very fragile, so right now, I have them placed in a drawer separated by a sheet of printer paper inbetween each one. They still have gum tape around the edges where they were stuck down and stretched to a board. Is this good enough to keep them in an okay condition?
