window boxes
Whether you choose to stain or paint the window planter box, save yourself some effort and apply your paint or stain halfway down the interior of the box. If you are painting, remember to prime the box first. Is a more weathered look your thing? Leave the box in its natural state and let nature run its course. I painted our window box in Behr's Deep Space.

I attached three nails on each side and vertically on the back piece, and five nails across the bottom of the back. To keep the boards in place, use a wall as support when attaching the sides. Clamps are also a great way to keep the boards secure. If you will be mounting your windowbox directly onto the wall, leave the front unattached so that it can be mounted easily. And for those of you who will be using brackets to mount the window box, go ahead and attach the front at this stage, too.
Use a saw to cut the boards to the desired length. The front and back pieces should be cut equal to the length of the window, including trim. The sides should be cut to a length equal to the width of the boards. Our window box was 40 inches long with 5 1/2-inch-long sides. The bottom was 39 inches long to accommodate the width of the sides. Drill drainage holes at least a half-inch in diameter in the bottom piece.
Attach the front to both sides and the bottom using the galvanized nails.
