Here is the final product of a recent job at the 1010 Building in Midtown. The tracking is a Silent Gliss Ripplefold/Wave system. The fabric is dupioni silk in taupe with black out lining. The Silent Gliss tracking lives up to its name- it's truly silent. The only thing you can hear are the ball-bearings gliding along the track. Now my clients can have some privacy and sleep past sun-rise.
