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.
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.
