I would do an inside mount shade instead. Roman, roller, solar, something like that.

You could attach the rod to the wall on that side like you would a shower rod or closet rod. But I can't find any photos of that...

Good luck!

I'm afraid it's too late for a shade because I found these beautiful dark plum curtains at the very beginning of my bedroom project and now HAVE to have them! Lol. Here's a pic of the room after the carpet, paint and new bed/bedding. Still need new furniture, lamps, bench, window coverings hung and walls decorated. Whew!

This is an L shaped curtain rod I think made out of pipe.

I thought Ikea had curved curtain rod/rail sections so you can turn a corner or turn them back to the wall for backout curtains.
