With the high cost of lumber these days I couldn't help but look for alternatives to the shadow box design Mark demonstrated in the videos. Strolling through the second hand shop the other day I noticed a large entertainment center that people just don't want anymore. They sit for a long time collecting dust. I recycled this one to make my shadow box. Mark's is very efficient. Mine has more style and storage in the base! I paid $125 but saved all that money on lumber. There was minimal fabrication. I just needed to cut a hole in the top for the light. I still need to close off the light leaks, and line the inside with black fabric.
