This house will have plain white curtains. They are 9" in length. I like tall curtains hung far above the window and puddling onto the floor. First, I pin the curtains in position on a piece of cardboard.
Then I spray with hairspray so it will keep it's form. You can also use starch spray for the same result.
When you take the pins out, the curtains stay the way you had them pinned. I use craft sticks cut in half lengthwise and painted white for my curtain rods. Next time- the finished house!
