Over the past few days I've been sketching a rock or two each evening. These are some of the more unusual ones picked up during our walks. The one in the lower right corner reminds me of a fossil but it's simply rock carved out by erosion. The red bits are red jasper; not sure of the other minerals. I had our youngest grandsons believing that the one in the lower left corner was a petrified dinosaur egg!
I painted these with a mixture of Daniel Smith and QOR watercolors, which are made with a different type of binder. I was curious as to whether they would "play nice" together --- they seem to work fine together.
