You can make a cute, cheap window treatment out of a tree branch. It's not as weird as it sounds. See for yourself! It's actually pretty cute!
All you need is a large tree branch, some brackets, a long piece of fabric to drape around the branch, and if you'd like, some dried flowers and ribbon to decorate it.
To figure out how long of a branch you'll need, just measure the width of your window/s. I found my branch at our city's municipal garage, where they take yard waste. Alternatively, if you live in a wooded area, you will probably have an abundance of fallen branches that you can choose from.
I cut the branch to the width of my windows, and broke off all the small twigs. Then, I installed the brackets. You can use drapery brackets if you'd like, but I actually used shelf brackets because I already had some. I centered the branch on the shelf brackets, and since they're flat, I secured the branch with some wire so it wouldn't fall off. I'd imagine that if you used actual drapery brackets, that wouldn't be necessary.
Once I had the branch up, I added the fabric. To figure out how long my fabric needed to be, I took the width of my windows, and multiplied by three. I then draped the fabric over the branch, and arranged it to my taste.
After I had the fabric in place, I thought it looked a little plain, so I decided to add some dried flowers and ribbon as accents:
I used ribbon to make a bow, pine cones, dried leaves, dried flowers, and the dried roots of a plant for these little arrangements.
Tie-top curtains would also look very cute hanging on a tree branch, as would beads. Painting the tree branch would also add a little something special to this inexpensive window treatment.
