Tutorial: How to make a wood valance window treatment

  • Leave a Review
  • I have been staring at the blank window in my living room for a whole year now. I kept thinking about doing a window valance tutorial and then kept putting it off. I finally decided I wanted to make a wooden cornice. I saw a similar version in a model home once and loved it! After doing a little googling, I decided to make one of my own, that way it would be unique. How hard could it be?

    It really wasn’t that hard to make…it just took time letting the glue and paint dry. It was well worth the wait though!

    We finished it last week, and I LOOVE it! It adds the perfect touch to our living room. This trim and scroll on the wood cornice adds a wonderful look!

    Do you recognize the crown molding? It’s the same kind we used in our kitchen makeover. It’s my favorite stuff. You can find it at Lowes.

    To make this you’ll need to start out with a long piece of MDF wood. Decide how long you want it and how wide. I bought a pre primed piece of MDF wood and had it cut down to 65” x 11”. Measure your window and decide what your measurements will be. I wanted a fairly large cornice so I chose 11 in. for the height but I think anywhere from 5”-12” would look great.


    I bought some trim to place at the bottom of the board to add a little more character.


    We glued that on using power grab.


    I also wanted to add one of these scrolly things to the base. I LOVE those things…whatever their called. ;) After everything was glued I added two coats of Swiss coffee paint.

    I had two 4” X 11” in. pieces as well to give the valance good depth. We attached these to the main board using L brackets to give extra support.

    After everything was attached we had to fill in some gaps in between the molding. We used wood putty for filling. That stuff can work miracles I tell ya. Once that was dry we sanded it down one last time and then I added one more coat of paint to seal the deal.

    We then attached some more L brackets to the wall, so we could attach the wood cornice. Look how boring that window is. Not for long!

    We also attached these wooden circles, so if I decided later to add curtains I could. These are found by the wooden rods at home depot. To hang curtains, you would buy a long wooden rod, and place it between the circles. Then you could hang your curtains from the rod. I found the awesome idea on All Things Thrifty. I plan to add curtains later… I just need to decide what color and find time to sew them.

    So what do you think of the window treatment?!

    I love how it turned out, and it looks great in our living room.

    It was cut at a 45 degree angle. It is more difficult than cutting normal base boards or chair rails, though. The trick is that when you are cutting it, you can not just lay it flat and cut it at 45 degrees. In the cutting box the molding needs to be standing just as it will be standing when you have it on the valance or else the angle will be incorrect when you try to put them together. Does this make sense? Sorry, it is a little hard to explain.

     As for the trim on the bottom, I cannot remember the exact size but I think it is about a 1 1/2 inch tall. We got it at Lowes in the molding and base board section. You can make it taller or shorter, depending on how big the overall cornice is going to be.
