Here is something that I wanted to do fo the past two years at least, but have only slowly made progress on it. My dad carved this picture into a board using a CNC machine before he left his job as a woodworker. He gave it to me for my birthday a couple years ago and I always wanted to paint behind the carving. Two years went by, and I finally got around to painting it. Another 6 months go by, and I finally blacken all the edges, sand it down and through a light oil finish on it. I like how it turned out.
