Remove door from hinges. Using measuring tape, determine the dimensions of your door and the spacing of the squares (for this project, we created three 22-inch squares). Using ruler and pencil, draw each square.
Place artist's tape inside the outline of each square; lightly rub to smooth.
Adhere painters' tape along the outside and inside edges of artist's tape=. For the strips of painters' tape on the inner part of the squares, miter the corners using razor to create a clean edge.
Remove artist's tape, and paint the space between the pieces of painters' tape. Let dry.
Wipe off pencil marks with a damp paper towel.
Repeat process with octagons. (Ours are 3/4 inch from the outside edge of each square.)
