Painting en plein air forces quick decisions and makes me to paint instead of over-thinking everything. When I decided to paint outside in earnest, I researched Pochade box options and decided I could make my own, custom box....a downside of having to be creative in every aspect of my life. Although it took longer to make and cost more than I thought, I have a nice kit for oil painting outdoors.
Later, I'll post links to sources that inspired the design.
Let me know what you think.
