Step 1: Start with an old wooden table
I used an old wooden dining room table. I liked the design of the legs and it gave enough room for pictures and decorations on top.
I cut it down using my circular saw to 15" deep. (All measurements should be made to fit how you might want it though. Your electric fireplace may be different than mine so shelves should be made to fit.)
After it was cut to size, I then spray painted it black.
Step 2: Next build the shelves.
Once I had all my measurements, I cut the shelves to size and spray painted them black, and screwed them together.
After they were all screwed together I used some 1 X 2 's to trim out the front. They were just nailed on with some finish nails.
