Trinity (FR Blackout), Aztec - Vertical Blind

Control position is a personal preference but generally you should choose the side that is easiest to reach and operate from, or will cause the least obstruction. 

If you choose a corded control option, you will receive a cord for tilting the vanes open/close and a separate cord for drawing the vanes to one side (your 'Bunch' option). These will be positioned on the same side, either left or right.

This Vertical blind is also available with a draw rod option (clear plastic wand) which would replace both the cords. You can twist the rod to tilt the vanes open/closed or manually pull the rod across the window to open or closed the blind. The draw rod is positioned to reflect your chosen 'Bunch' option so that you can draw the vanes to which side you select. 

All our blinds are manufactured to be child safe so a control cord retaining device is sent out with the blinds to be fixed to the wall corresponding to the chosen control side.
