How to make a dollhouse curtain rod:
Spray paint your wooden dowel the color you want. I choose white, but black or brown would look nice depending on the scheme you’re going for. I would make sure the color matches the cup hooks. You can always paint those if you need to as well.
Take two of the cup hooks and screw them into the dollhouse wall above the window. These are super easy to use and I suggest keeping a pack on hand because they are useful for a lot of things in a dollhouse.
Hang your wooden dowel on the hooks and you have yourself a dollhouse curtain rod!
