After sanding and painting the table, she got started on constructing the new sides. She cut sections of wood into 1 foot by 2 inch strips to form the bases that make up the squares and then one 2 foot x 2 inch strip to create the new bottom or base. Then, she joined all the pieces together with wood glue and dowels by drilling a hole in the end, filling it with glue and sticking a cut piece of dowel inside. To join it to the rest of the structure, she drilled a hole in the adjoining area of the corresponding piece of wood, filled it with glue and stuck the first dowel inside it. Be sure to wipe away any excess glue.
