Drill Holes Inside Each Panel

  • Use scrap pegboard as a guide to drill pairs of ¼-inch holes along the inside of each side panel. 
  • Space pairs of holes about 9-inches apart horizontally and every 2-inches vertically. 
  • Drill the holes 3/8-inches deep and use a depth-stop bit attachment or a scrap block of wood as a guide to make sure you don’t drill all the way through.

  • Cut the pieces to size and miter the ends as necessary. 
  • Cut and fit the trim moulding around the top of the unit. 
  • Use a nail set to recess all nail heads.
