If you have a bay window, then you may empathize with me. Those curtain rods are crazy expensive! I have a total of three bay windows in my house. When we first moved in I looked everywhere for an inexpensive rod, there were none to be found. So I resorted to using a swing type rod and made do.
Over the next few years, every time I stopped by certain stores I would look to see if there were any rods on sale. No luck.
I used Pinterest to search DIY rods, and found a good one where they used a bendable metal pipe. I got one and tried it out. Then put it in the basement and forgot about it.
Finally, I came across a blog (don't remember which one) that showed how you can use a bendable curtain rod from Ikea to make a bay window rod.
Here is what you will need:
2 of these bendable corner connectors ~found here
2 of these shorter rods~found here
1 of these longer rods~found here
and 4 of these brackets~ found here
And there you have it, about a $25 bay window curtain rod.
