Finished! On an art supply bugdget of $0, I cannabalized my daughters’ little easel and used a beveled glass shelf from my wife’s curio cabinet to create a collapsing light box. I had rigged it a while ago but it didn’t colllapse and I had no practical way to store it. Problem solved! Now if I need it I can just break it out and set it in front of my desk lamp for instant light box action!
