I purchased this item to use to make acrylic skins based on the recommendation of several artists. So far I have only used the sheet wrapped with parchment paper although you can use heavy plastic bags or an old shower curtain. I have tried the sheet not covered with parchment paper with paint that wasn't very good quality & the results were mediocre. I am going to try to make skins with a pouring medium & golden paints & I suspect the results will be better. Recommended for acrylic skins by several artists.
