only using the 20" x 20" column patterns shown above. Complete the column
layers as illustrated above alternating with one of each layer per column. Secure

front of the bench to create the seat as well as the wall that creates the bench’s
backrest and columns. Secure the cap units with exterior grade construction
adhesive. Complete the look with outdoor furniture cushions, wood or another
material of your choice, and pillows to make your bench more comfortable.
