We used Open shutters for this little girls room. The window, which was actually a void looking down over stairs required something to block out the light, provide something solid and safe and also filter light during the day that comes in through the ceiling to floor windows in this Hunter Valley home.
For the theatre room it needed to be 100% block out blinds. Peter Meyer's channel blinds with a 100% block out fabric solved this! In reveal channels were installed that completely block out the night making for a great cinema like experience.
