How to hang curtains in a bay window
Choose tension curtain rods if you want something easy to install.
Tension curtain rods are straight curtain rods that go inside of window frames as opposed to above them. The ends of the rod will push against the sides of the window frame so the rod stays in place.

You can find rods with a little space left over to hang or you can purchase tension rods with extra length to spare. (II) Tension curtain rods range in price from $20 to $300, so ask around and people may be willing to bid. You can find tension rods online or at your local home improvement store. (III) Read your specific window frame's requirements to determine the best, tight fit for your window. Your only risk if using tension curtain rods is if you live in an area with cold winters. (IV) Tension rods are cheaper than other curtain rods, and they don't require any drilling to install them. If your bay window has 3 window frames in it, you would need 3 tension rods.
