Easy Half Moon Window Treatment

Megan Shoop

Half-moon windows sit above front doors and over tall windows in dozens of homes. Some homeowners like these windows, appreciating the architectural interest they bring. Others would rather not have them because they let in too much light and can be difficult to cover.

However, there are several covering options that are simple, fast and work for both kinds of taste.

Window Inserts

Make window inserts to cover your half-moon window completely. Make them from wood or thick, sturdy cardboard. Cardboard is easier to handle while wood is thicker and provides more insulation.

Begin by measuring across the bottom of the window and from the bottom of the window up to the highest point of the arch. Transfer these measurements to a piece of paper, drawing a horizontal line for the base and a dot above the line to mark the arch. Use a mathematical compass to draw curves from either side of the dot to the baseline. This creates a pattern. Trace around the pattern onto cardboard or wood and cut it out with scissors or a handsaw.

You have several options. Paint or cover the insert with wallpaper to match your wall so the insert looks invisible. You could also draw, paint or carve the surface of the insert to make it decorative. Secure it into the window with wood glue or caulk around the edges.

Window Film

Use window film as a decorative way to obscure light coming through the window. Window film is vinyl film printed with stained glass patterns that clings to glass just like holiday window clings. It is available in dozens of styles, colors and patterns, usually arriving in large rolled sheets.

Choose from frosted window film with white and clear patterns or choose floral and other traditional stained glass patterns. For a trendy twist, many companies sell geometric and abstract stained glass window film patterns. Explore the Wallpaper for Window website for more options.

Cut down your window film to fit your window by creating a window pattern as you did for the insert. Line the flat edge of the pattern up with an edge of the window film. Use a utility knife to cut out the arch. You may trace the pattern and cut it with scissors, but make sure you use chalk so you can clean up the edges. Press the window film into the corners of the window and smooth it upward into the arch. Use the edge of a credit card to smooth out any bubbles.
