Painting with Watercolors, Glue and Salt. This looks fun! Use canvas or Water color paper, and paint with watercolors by using brushes. Drizzle clear Elmers glue all over the painting, then sprinkle kosher salt around the painting to give it some texture and sparkle. Wait for it to dry and instant awesome art! I don't know if I want to wait for Lilly on this. I want to do it!
