These were painted on 300 lb cold pressed paper which is quite heavy. Once the paper is wet, the paints blossom in lots of different directions and it makes for interesting effects. The downside is that this paper is quite expensive so you want to think about what you are going to paint for a while. Notice the little flower with the strange center in the second painting. I thought the effect was intriguing. The last one is of some flowers I put on Annie's birthday card.
