Al Fresco Art Club Challenge -- Get Out of Your Comfort Zone

Today I decided to challenge myself by doing another gouache painting. Gouache is the medium I’m least comfortable with. I used a single acrylic 1/2-inch flat brush to paint a green plastic lawn chair. I decided to change the colors a little because I didn’t have premixed colors that made me happy.

My goal is to learn to paint using the least possible amount of gear, and, if possible, to be skilled at painting pictures using only a single brush. I’m looking for one brush to rule them all.
