Here are my starting materials: two antique milk glass door knobs, a wooden dowel, two wall hooks, and silver paint. Not pictured are store bought curtain clip rings, Liquid Nails, and the curtain, which is actually a tablecloth.
I painted the dowel. Then I put the curtain rings on the dowel. I used Liquid Nails to glue the dowel into the two antique milkglass doorknobs, which conveniently I bought without the rods that attach them to the door mechanism. The only problem with the way I created this curtain rod is that the curtain rings are now permanently on the rod, unless I want to break the dowel to remove them.
After everything had dried and cured, I attached the rod to the wall using the wall hooks which simply screw into the drywall and studs. [Wooden dowels come in multiple diameters, so I picked the diameter that best fit into the door knobs. Similarly, I bought wall hooks that best fit snugly around the dowel.]
For the curtain, I used a hand painted piece of fabric that my sister gave me, which I think is from Bali. I am pretty sure it is supposed to be a tablecloth, but it fit my window perfectly, and it was too pretty to never have on display. Below is the finished window treatment that is pretty and VERY unique.
