Deco foam comes not only in pre-cut shapes, but also in sheets. For an uncommon and three-dimensional look, cover your window-topping cornice board with foam sheets. Use one solid color to cover your entire cornice board, spraying your rough wood board with craft adhesive, then attaching the sheets, or clip sheets of two colors into squares or rectangles and arrange them in a checkerboard or striped pattern, creating a simple yet engaging cornice.
Transform bland curtains into more decorative ones by attaching deco foam shapes. Take a set of solid colored curtains and attach deco foam shapes that fit the decor using fabric glue. For example, add deco foam flowers in deep red to bold yellow curtains, placing them randomly around the curtain panels to make these a more fitting addition to your daughter's floral-themed room. Because adding these shapes is a simple task, you can even engage your child in this home decor project.
Dress your windows up for the holidays using deco foam shapes. Purchase some shapes that are thematically appropriate for the upcoming holiday, such as deco foam eggs for the Easter season. Using translucent thread and a needle, run a piece of thread down through the deco foam shape. Allow a length of string to extend from the top of the shape. Using translucent tape, attach this string to the top of your window well, placing each shape at a slightly different length from the ceiling to create an engaging and holiday-ready display.
If the hooks from which your curtains hang are visible, turn some attention to them, dressing them up with deco foam. Select hangers similar to shower curtain hangers, looking specifically for ones that feature flat, round or square faces on the front as these are easiest to cover with deco foam shapes. Use craft glue to glue a deco foam shape on the front of each of these hangers, jazzing them up and making them more whimsical curtain toppers. This option is particularly wise if the shape you elect to glue is one that would hover overhead, such as a cloud or a balloon, as the placement above the curtains will seem more apt.
