I did this one on hot press paper and really enjoyed it.
I also just placed an order for some aquabord and am excited to try it out as well. A friend of mine made a cute colored pencil drawing of a giraffe on the aquabord so I want to make something to go w/ it. I will post the pair when I finish my part. http://www.dickblick.com/products/ampersand-aquabord/
