Cut your 2 x 2s into four pieces of 16" and eight pieces of 12" using the circular saw.
Sand all the wood and remove any dust with a tack cloth.
Stain your wood - brush on the liquid stain and wipe the excess off with a cloth. Let dry.
Pre-drill and countersink the 2 x 2 pieces together, with the 16˝ pieces forming the legs, and the 12˝ pieces forming the support between the legs. Set aside.
Place a paver down on the ground. Place two of the 16" pieces on each side, and one 12" piece at the bottom. Place a thick bead of adhesive along the inside edges of the wood frame, glue to the paver, and then screw the wood pieces together.
Repeat step 5 three more times to make four sides.
Set the four paver sides in a square with the bottoms up, and place beads of adhesive along the bottom of the concrete pavers.
Place the base into the adhesive and set the remaining screws. Place a bungee cord around the planter and let dry overnight.
To finish, line the planters with landscaping fabric and add the plants of your choice. You can also drop pots directly into your planters.
