We have a difficult window to curtain. It's deep and relatively narrow. The reveal is 16 cm deep and absolutely square sided. The window (traditional Scottish sash) is near enough 100 cm wide, 140 cm high with the sill at 100 cm.

The problem is the curtain rail which requires sharp angles over a fairly short distance.

The question is - would a corded rail work better than just a plain pull-the-curtain type?

Thanks
