Step-by-step Instructions
Step 1
Cut the 3/4" plywood to an 8-1/2" x 8-1/2" square, then cut corners off at 45 degrees.

Step 2
Set a circular saw blade to 3/4" depth and notch out the 2x2 cross supports as shown above, cutting the long side on one and the short side on the other. Glue (don't screw or nail) the two pieces together.

Step 3
Build the stool using either 1-1/2" pocket holes and 2-1/2" pocket hole screws or countersinking wood screws (2-1/2" long would work).

Step 4
Attach the outer foot rest with 2-1/2" screws countersunk from outside. You'll only need one screw per joint. Use glue.

Step 5

Finishing
Sand all surfaces, starting with a medium grit and finishing with fine. Wipe off the dust, fill any holes or gaps with wood filler, and sand smooth once dry. Apply primer if you're painting, then finish with your choice of paint or stain and seal with a durable clear topcoat. For outdoor projects, use exterior-rated primer, paint or stain, and sealer so the piece stands up to the weather.
