Architecture school involved lots of translucent papers, especially drafting vellum. I still love translucency, and decided to try monotype printing (using a gel plate) with drafting vellum. (Note: this is a cotton product - there is no calf skin involved, I'm not THAT old timey.) It is nice to see the plate through the paper, and I find the air bubble textures, where the vellum resists the paint, interesting.
