I visited a really cool art store (PLA-ZA) while I was recently in Nashville, and one of the things they had was watercolor markers. I have become somewhat familiar with watercolor pencils, but had not seen or tried markers. I was totally giddy! I decided to buy one to play around with (a Winsor & Newton in sepia), and here is a butterfly I just quickly scribbled out with it. The pen was very smooth, and I was able to draw almost brushlike strokes and fine lines using both sides of the marker. It also goes on a bit darker with the brushtip, so you can achieve some color variation! I will have to get more colors and see where they take me!
