We tried to put the blind up but it did not have any fixings to attach to the velux window. Its now lying on my desk in two pieces. There were two red/orange tassels which seemed to go nowhere. Two handymen tried to put it up without success. It was for a Spa treatment room, where the therapist wanted to blackout the sun. Even if it did fit, the sun shone through it as we were attempting to attach it, blocking out no light at all.
