To begin, cut the lumber according to the cut list using a miter saw.
Lay five 16” 1x4s together with their long sides butted up against each other. Place one 16” 2x2 on top of the 1x4s on each side as shown above. Nail them in place with a brad nailer.
Now, lay five more 16” 1x4s together and rest one of the finished side panels on top, butting it up to the edge. Nail in place. Repeat by adding the other finished side panel to the other side.
Next, lay the final five 16” 1x4s together and place the 3 attached side panels on top. Nail in place. Now, add the 20” 2x2 leg pieces to each outside corner of the planter with wood glue and brad nails, ensuring the top edge is flush with the planter.
Next, create a platform inside the planter a few inches from the bottom by nailing the 12” 2x2s to 2 sides inside the planter and nailing the 3 scrap wood pieces evenly spaced on top.
Finish the planter by attaching the 4 angled 15” long 1x4s to the top of the planter with brad nails.
