I currently have uPVC tilt and turn windows. They’re rather ugly and I’d love to replace them, but after doing a costly renovation, don’t have the funds to replace them as they’re in good condition! However I’ve struggled with window dressing. I’ve gone for curtains and voiles in some rooms but for others, have gone for Roman blinds outside of the recess. They look ok, but I’d like to have a sheer roller blind or something underneath for additional privacy as I live on a busy road. I obviously can’t put roller blinds under the romans outside of the recess so I was thinking of putting them on the upvc part of the window frame, which would mean drilling into the frame. Has anyone done this? Or have any other ideas? Thanks!
