Article: Always remember, measure twice, cut once. You only get one chance at cutting before you make a mistake and discover that you have to make another trip back to the hardware store. And they will immediately know why you are there. Cut the longer pieces first, then use remaining pieces for the shorter sides or to create braces. If you can apply a sealant or paint before final assembly, do so. The purpose is to coat the wood, and so why not make sure that it is properly covered before screwing all of these joints together forever? Though there are devices that will allow your to drill the screws directly into the lumber, doing so can stress the wood and cause splits near the end. It is also easier to maintain control when drilling guide holes than it is to screw directly into the wood, especially when using hard woods. Use a screwdriver bit with your drill to attach the ends of the window box to the bottom using rust-proof screws. Be sure to support the wood against something sturdy or have someone hold the lumber while you are screwing the pieces together. Place the front and back sections onto the bottom section to make sure that all of the pieces are cut to fit (the ends should all be flush with each other) before attaching the front and back pieces of the window box. Screw the front and back pieces to the bottom and sides of the window box. You'll need several holes in the bottom of the window box to allow water to drain out of the window box. Let the sealant or paint dry completely before final installation. This will prevent the soil from rotting the wood. Use them to cover the drainage holes to keep the soil from coming out of the bottom of the window box. Drill holes into the exterior wall where you're going to hang your window box. Additionally, if you have left lumber to serve as a separate brace, drill holes for that as well. Attach the brace first, then the  window box, screwing them in tightly but without damaging the wood. When screwing the window box to the brackets from the bottom of the window box, use screws that are slightly shorter than the thickness of the bottom of the window box. Your project is complete.

What is a summary?
Measure and mark the pieces of lumber for cutting. Use your saw to cut the lumber to desired lengths. Sand and, if applicable, seal or paint the lumber before assembly. Drill guide or pilot holes into the lumber where you plan to screw the pieces of lumber together. Assemble the box. Drill drainage holes. If appropriate, apply additional sealant or paint as needed. Insert a plastic window box liner. Cut small pieces of weed cloth. Install the window box. Add soil and flowers, plants, and/or herbs.
