If you're referring to @Amanda's post here http://www.hometalk.com/1380691/diy-curtain-rod-for-oversize-windows , click on the "Post comment" link just under the post and ask your question there. I'm sure she'll be happy to give you a hand. She also has more details on her blog post http://cupcakesandcorndogs.com/2013/04/diy-decorative-curtain-rod-for-under-20.html . Good luck!
Yes Linda, if you were speaking of my post, I used electrical conduit and spray painted it black. All of the details are in the link that Yair posted. Thanks @Yair Spolter
