To begin this woodworking project, we'll need to cut a full sheet of 3/4" sanded plywood down to the appropriate pieces. In all of the steps of these free woodworking plans, the pieces will be built according to the 24" x 24" x 48" planter box described in the detailed free woodworking plans.
Using your table saw or circular saw, cut the following pieces from the sheet of plywood:
2 @ 24" x 48" - Sides of the planter box
2 @ 22-1/2" x 23-1/4" - Ends of the planter box
1 @ 22-1/2" x 48" - Bottom of the planter box
Sand the cuts with some sandpaper or a random orbital sander.
