All I did was cut MDF into my desired size. I have the cornice 1.5 inches longer on each side than the window and 3 inches sticking out from the wall. My roman shades are inside mount, if you have an outside mount shade you need to adjust that accordingly.
You can see in the below photo how I screwed the pieces together. I also used some liquid nail glue to make the connection even stronger.
Don’t forget to pre-drill your holes with the countersink drill bit, so the screws sink in flush with the MDF board.
All you have to do after that is attach your batting with a stapler and then stapling your fabric over that.
I ended up letting some of the fabric hang over the actual cornice when I stapled fabric to it the second time. In the above photo you can see what I’m talking about. I was actually too lazy to remove my first fabric and just stapled right over it with the next one. Thankfully you can’t see it from the outside of the window. That would be a no-no.
I have no clue where I originally got the hardware from to hang the window cornice. I found it in one of my toolboxes but they work great. I have them on both sides and I can take them off or hang them very easily.
Below is a recent photo of my kitchen with another new fabric on the valance. (click HERE to see the post)
The dotted fabric is from Ikea and you can read some more about it HERE.
So that’s it. Not very exciting isn’t it? Ugh, actually very boring.
It’ll be more exciting to work on my powder room. Let me tell you the sanding of all those diamond lines is horrible.
