Good decorating ideas using Styrofoam cornices include crafting a base for valances and window treatments and creating decorative wall boxes when covering the cornices with colorful or neutral-tone fabric. Styrofoam cornices are also used to create corner shelves to display lightweight decor accessories. Cornices commonly serve as a base underneath fabric to create shape for the window treatments or wall decor.
Styrofoam cornices are most commonly used to craft window treatments and valances, and they allow homeowners and decorators to create the underlying structure outlining a window. The Styrofoam cornices are then covered in fabric to create a blocked-off look at the top of the windows. Styrofoam cornices can be attached or situated directly to brackets on the wall when crafting valances. Wrap the desired fabric around the cornices, and sew the fabric together, or attach with crafting or hot glue to tighten the fabric.
Homeowners and decorators typically need Styrofoam cornices that match the length of the window or the desired decorative shelf. The cornices can be cut to fit with an X-Acto knife. Some decorators use picture hanging claws, hooks or nails to attach the cornices to the wall. The use of thick fabric or batting creates a bulkier look to existing decor.
