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 (using the jointer and planer). If you are using previously surfaced lumber, you can omit this process. Rip the board to the width that you want the frame to be. Then crosscut to length. Squareness is critical here, so we recommend that you confirm that your tools and fences are square. If you have a planer you may want to send all pieces through on edge and side-by-side to guarantee that they are identical.
