Drill pocket holes in the 12" board with 2 pocket holes on each end.
Drill 4 pocket holes in each 5-1/2" board, with 2 holes facing each direction. Be sure the holes do not overlap.
Assemble the center support by attaching the two 5-1/2" pieces to the 12" piece using wood glue and 2-1/2" pocket hole screws.
Mark the location of the support assembly on each leg. We positioned ours approximately 6" from the bottom of the legs.
Attach the center support assembly to two legs using wood glue and pocket hole screws.
Attach the remaining two legs to complete the stand, checking for square as you assemble.
Cut decorative beaded trim to fit each leg. Apply wood glue to the back of the trim, center it on each leg, and secure it with 3/4" pin nails.
Fill holes if desired and sand the entire project smooth.
Apply stain, paint, or a protective finish and allow it to dry completely before adding your planter.
