Get an adjustable bracket and make it fit what you have

This one is adjustable but it is as small as it will go.  Do you know of a small bracket?

I googled ”short projection drapery rod bracket” and found some choices. You will have to find a bracket that will fit your current rod diameter. Don’t let the bracket color deter you—they can always be spray painted. Hope this helps.

Ratherbesewing, thank you but these are the same size brackets as what I have.

Jan, thank you, that would work but the return on the drape isn't wide enough to reach the wall. I am using the smallest bracket width that I could  find.  I have ordered dozens of drapes and none have returns wide enough.

Can someone show a picture of this working?

The problem is less the return, and the bracket: The curtains have the last grommet placed TOO CLOSE to the end of the panel for ANY bracket. !!

As below:

The bottom of the screw eye must line up with the top of the rod, as it now sits. The squiggles I drew: That fabric, AND the grommet, will be UNSEEN by you when you stand in FRONT of the curtains. They will be against the wall.

Why it will work: The distance between the grommets, is GREATER than the one inch of fabric you have at the end of the panel and past the last grommet. There is no such thing as a two inch return bracket, and you do not want to buy a "return rod"......and problems as this is why the return exists!!!

You either try as the photos above, or you buy better quality panels, or buy a return rod

Are the panels wide enough that you could have the panels altered?

Cut at the orange line -

Remove end grommet

Patch grommet hole with lining material from the fabric that was cut off.

fold in and create the new seam at the blue line.

@JAN MOYER - Love the cup hanger -- easier than my solution and would fix the issue! Keeping this idea in my arsenal!

It's very easy- absolutely do not cut the panels : ) lol

All the fabric and dotted line ) all the area right of your blue line, will simply be hidden and against that wall.

(adding the comment for the op, not you.......who gets it : )
