Media used here: watercolor (several brands and types), masking fluid, pastels, and gel pens.
My was my first attempt at using masking fluid for both writing and drawing. I can see many applications available with this product, though I didn't have much success using it later with acrylic paints. (I think the paints were not dry enough when I attempted to remove the masking fluid; a lot of the paper beneath tore. That was not a happy experience, but I am committed to try again with the acrylics to determine the exact cause of the near disaster.)
