I found a great tiny watercolor kit from Japan called Koi. You can see the brush just under the paints. The brush holds water so I do not need to bring a water bottle. I just put my journal and this Koi paint kit in my handbag and it is all that I need to make small watercolor studies anywhere I go; museums, views from my car, or to work out ideas before I paint a larger work. I love it. It is a great way to make color thumbnail composition studies. These two small studies are of two works by the artist Kim English. The second one of the girls eating lunch reminds me of me and my sisters when we were young. He is amazing when it comes to plein air painting.
