I decided to create a cornice with sheers!
Most cornices I had seen were made of wood and I was concerned about the weight. I didn't want large holes in the wall and having to worry about the fixture pulling out of the drywall. I don't know if I saw this idea in a book, or thought it up myself (we're talking about 25 years ago) but I made it using foam board and a hot glue gun! And it worked out perfectly without costing me an arm and a leg.
My granddaughter Brittany, recently moved into her own apartment with sliding glass doors to the patio. Unfortunately, she wasn't able to put up a decorative rod, but the door just needed something more to look finished. So, I suggested a cornice that could be attached to the top of the door frame.
Polly, over at "Learn and Go" blog has a tutorial that was very close to the way I made it.
