If Using a Pre-Built Frame

  • L-brackets
  • Screws
  • 2x4 for framing made of appropriate wood


  • Use a straight edge (such as a long level) to mark where the crown molding will sit on the cabinet facing. I recommend at least 1 inch of space above the line to attach the trim. If you have cabinets that don't have enough room to attach directly, build a frame to sit on top of the cabinet. The frame measures the exact same size as the sides and front of the cabinet.
  • Measure or hold the piece of trim up to the cabinet and mark the length for cutting.

  • Start on one end where the molding meets the wall and work around one corner at a time. Cut both pieces before attaching. For outside corners, I make the first cuts usually about 1/16 inch longer than my pencil marks. This allows for room around the curve and gives a little room for testing the angle.
  • To attach after cutting, use wood glue and nailed across the bottom where the boards meets the frame. Nailing at slight angles will assist with holding it tighter and resisting pulling away.

Tips for Cutting
  • Never assume your angles are perfectly 90 degrees. Mark them before cutting.
  • For outside corners, I cut about 1/16 longer than the measurement. It just works better that way for me.
  • If you have trouble holding the trim against the fence, cut a scrap piece of wood in a triangle that is the size of your gap.
  • Generally speaking, I don't do the "cut the leading edge" trick. I usually cut the inside corners first (one at 45 and then mark the opposite piece for the leftover angle), then work outward from that corner.
