I've been wanting to see if I can paint while sitting in my car because I'm just no good at cold weather. It was pretty messy and cramped. Tried to use my Easy-L paint box on my lap but the seat wouldn't go back far enough so I had to do it kind of sideways.
I plan to try again with a tiny paint box my husband made for me when I first started painting outside. I much prefer standing but I'm going to try to figure this out so I can paint outside this winter.
