I painted the outside with Benjamin Moore Balsam color paint (as another poster on here did) and stained the interior pine with walnut stain. I tried making it resemble a pine tree. I wanted to make it as sturdy as possible, so I used 1/4 inch plywood backing for the entire back, and secured it with 1 inch brad nails. I painted the edges of the plywood green and left the middle unfinished because I liked the look.
