Even after a dozen years, it still surprises me that I can draw on my iPhone. The app I use now is called Pocket. It is the iPhone version of Procreate, the drawing app I use on my iPad. It is easy to use and very powerful. Pocket can do most things that Procreate can, including making animations! What I like it best for is making sketches when I am out and about. My ‘Look Ahead” series was made entirely on the iPhone, with renderings full of detail and nuance. It excels at sketches. This is yesterday’s sketch of our new willow tree. We planted it last fall to sop up the water in a boggy hollow behind our house. It has turned bright yellow in the spring, the color seems exaggerated, but it isn’t really.
