A fresh coat of paint

Painting the wall isn’t really necessary but it can make the wall look a little nicer and can improve the lighting situation if you use a light color. I applied one coat of the cheapest white I could find at the local paint store. Since I had concealed most of my corners and seems the paint gave the surface an immaculate appearance — perfect for boot rubber, pencil, chalk, and marker drawings, stickers, and other fun stuff.
