Find an inspiration image — or print something off your computer — that you can trace upon the plywood. Draw the cut-out pattern directly onto the plywood using a pencil.
Use a jigsaw to cut out the shapes along the sketched lines of the silhouette. Remember to wear safety glasses. Use an electric sander or sanding block to smooth out the edges of the silhouettes.
Spray-paint the silhouettes the same color — and in the same manner as the trim pieces. Apply two coats.
Using a caulk gun, add a bead of liquid bonding adhesive to the back of trim, then place directly onto the door front. Repeat this step for all pieces of trim, lining up each mitered corner.
Add liquid bonding adhesive to the silhouettes, then press them into place. Allow the adhesive to set for at least six hours before turning the cabinet upright.
