Cut the pieces and trim for the drawer fronts. These will be assembled in the same manner as the work surface. After assembly, drill holes for the knobs or handles. Shim the drawer fronts in place (there will be a 1/8” gap around all sides) and drill screws through the holes for the knobs into the drawer boxes. Open the drawers, and secure the fronts to the boxes using countersunk 1-1/4” screws from the inside. Remove the screws from the knob holes and finish drilling out the holes.
