do you want the panels to close? that is, will the swing arm rods be long enough to meet in the middle, or just be on the sides?

i find even well made ones sag a bit, we had to put a screw in above our door window to support the ends.

I don't want them to close. Just one panel on each end.

Dang. It ate my comment.

I did single panels on each side of a long horizontal window in my bedroom; the bed has to go on that wall. No way I was going to close the drapes and it seemed a waste of material and money to do it the conventional way.

This is my knock-off of a very expensive rod from West Elm:

The hardware came from Amazon and I painted them gold. The end caps are from IKEA and are also painted. The rod is a cut-down 36" dowel from the big box store that I stained. The drapes are also IKEA white cotton 90" length. I used TWO panels on each side; one looked too skimpy. I hemmed them with iron on tape after hanging. I might replace the old white mini-blind with a woven blind, but I do close it at night and it doesn't bother me that it isn't all that trendy.
