Prepping and Assembly:
Sand the wood well before beginning to cut and assemble the pieces.
Use wood glue along the seams and a finish nailer to attach the braces. These should be placed 4-6” from the top and bottom of the panels. A single coat of white paint and a light sanding after it dries will allow the wood grain to show through. You can also use a wood stain rather than paint.
When the paint has dried, attach the hinges:
Attach the knobs and hook assembly and then install the hinges from the outer panels to the window frame.
