Best way to keep watercolors and acyrlic paintings from decaying?
I have a client who has small paintings on watercolor type paper. She wants to preserve them as best she can. As of now they are covered with wax photo sheets and stored in plastic boxes. She wants to keep a few and then dispose of the others at some point, but in the meantime, she wants to keep them as pristine as possible.
Anyone out there who has dealt with this kind of project?
