You're most welcome! Yeah, I struggled awhile back trying to figure all this out all by myself, so I felt compelled to help. From my experience, get the thick plywood and turn it into your painting panels. They last forever! Imagine spending hours working on your paintings, yet they warp or do not last "forever", you know?
Again, glad to help! Keep up your great work!
