Awesome idea!! I’ve been on the Ross-TJ Maxx hunt for cheap curtains and rods, but I think I’ll opt for your idea. I love how candid you are about your “ghettoness”. I feel as if it can be rigged, I’ll figure out a way to do it!
I have done this a couple of times. Even cheap curtain rods are more expensive that doing it this way, and the bonus is that you don’t need a center support because the conduit is not flexible, just make sure your hangers are in a stud, which you can usually find because you are putting the hangers at the end of the window where it is framed. I did this in my sunroom and took steelwool to the pipe because everything in my room is stainless steel. Looks awesome and even better, it is one solid piece so you don’t have the part in the middle where they connect and the rings always get caught up in it.
