The art therapy class I took last fall really opened my eyes up to different media. I had never painted with watercolors before, and now I'm crazy about them! The painting above was done with watercolors and Sharpie, which I found to be a wonderful combination. See more of my work below.
I encourage you to try watercolors. Just experiment, get to know them. Then if you like them, try adding another media, like ink, crayons (which will resist the paint for lovely effects), or collage materials.
