There are a few things you need to do in order to make a cup holder for your car. First, you will need to find a piece of wood that is at least 2 feet long and 1 inch wide. Next, you will need to find a piece of metal that is at least 1 inch wide and 1/2 inch thick. Finally, you will need to cut the metal into two pieces that are the same size. Once the metal pieces have been cut, you will need to fit one of the metal pieces into the wood piece. Finally, you will need to fit the other metal piece into the top of the cup holder.
