Tested a couple old brushes using a dozen watercolor half pans on illustration paper. Purchased the art supplies for a book cover illustration project a few years ago. Have not had the occasion to use them since then. Apart from recreational sketches and practice.

Painted some studies of graphic design advertisement posters from the 1960s. Muscle memory atrophied more than expected. How does the aphorism go? Either control the watercolors or they will control the painting. Some clumsy mistakes. A good test of skills. Not ready to paint a book cover illustration. But the exercise warmed up the muscles and mind to consider more opportunities.
