I recently researched alternatives to glass for permanent framing/protection, and I found that glassine paper is supposedly a good cheap alternative. I ordered it on Amazon, but I was very unhappy with it. It was barely transparent and the glassine obstructed the viewer from seeing my art and appreciating the colors and the beauty, it was like looking through a smokey window. So now I'm looking for any other suggestions for paper that would protect my art and have a generous amount of transparency.
