Now that you have all of the tools and materials, we can jump right into the project. Let's start by preparing the wood for the frame. We started with one piece of walnut lumber and surfaced two faces and one edge. If you are using previously surfaced lumber, you can omit this process. Next rip the board into four equal strips as shown on the image to the right. If you have a surface planer you may want to send all pieces through on edge and side-by-side to guarantee that they are identical.
