Bumping this because I don't think the solution I found will work.

These are the initial rods I bought.

It seems as if we must unscrew the rods from the wall if we need to remove the drapes.

The Umbra twilight room darkening rods I found (pic below) might not be the best solution either. Lifting the rod out of its "nest" attached to the wall risks damaging the paint on the wall.

Could someone please tell me what's the best way to hang blackout curtains?

Karenmo, those rods didn't work for us and I ended up contacting a designer and getting a semi-custom solution.

How important is that little slice of light you may have with just regular rods?

Tartanmeup, I am wondering what rods were used for your project?

Not as important as initially thought, ritasj. We went with something like this with wave drapery, Karenmo.

Ah, that is a lovely traversing system, tartanmeup!

Thanks, Karenmo. Spendier than I wanted but yes, it works well.
