Halloween Window Decoration

Turn windows into ghostly shapes for Halloween by trimming them with these curvy coverings. They’re easy to make and install in any room you haunt.

Halloween Window Decoration


Step 1: Cut the foam board to a size that’s 2 inches [5.08 cm] greater than the length and width of your window. Print the window decoration pattern and transfer the design to the foam board.

Good to Know: The design can be customized to fit most window heights and widths. When sizing up your windows, measure from the outside edges of the moulding.

Step 2: Working outside, cut out the opening using a jigsaw or the narrow tip of a drywall saw. (Save the cutout for future projects or insulation needs.) Sand the cut edges smooth with 180-grit sandpaper. Vacuum debris clinging to the foam and thoroughly remove dust from the surfaces using a damp cloth that reduces static electricity as you wipe.

Step 3: Apply two coats of paint to the front, back, and edges of the board.

Good to Know: Painting both the front and back face ensures the colour of the foam won’t reflect in the window or show from outside.

Step 4: Have a helper hold the foam in place centred over the window. Using black nails, fasten the foam to the window trim. Repeat for the remaining windows.

Good to Know: After Halloween, you can fill the tiny nail holes using coloured wood filler.
