This easy-to-build box is perfect for a kitchen window sill or countertop. If you plan on keeping your planter box outdoors, use a species of wood that is weather-resistant and line the box with a plastic wrapping.
We did not finish or paint our box, instead we left it natural and added a pop of color by painting the clips a bright neon color.
5 pieces of wood (we used maple): 2 measuring 5-1/2" x 5-1/2" (end pieces); 2 measuring 20" x 5-1/2" (sides); and 1 measuring 18-1/2" x 5-1/2"(bottom)
neon spray paint
extra finishing nails for reinforcement
waterproofing tape, such as Tyvek
Lay the bottom piece of wood (the 18-1/2" x 5-1/2" piece) on a work surface and apply a small bead of wood glue all away around the edges. Adhere one of the side pieces (20" x 5-1/2") to the bottom, lining it up in the center. This will leave 3/4" overhang on each end.
