A few nights ago, Handy Hubby got to work building the cornice for me. It took him about 30 minutes total and that included digging around looking for wood scraps in the basement. Here are some pictures of the final product. It's pretty straightforward.
It will hang from a French cleat which is basically two pieces of wood cut at a 45 degree angle which fit together by sliding one down on top of the other.
Here's Handy Hubby screwing the wall cleat in with drywall screws.
And here he is testing the fit to ensure it's level.
And here's the (almost) finished product.
Next up - fabric!
