072902-download-1

072902-download-1

Choose motor side for centre opening

Mike’s Tip:

Choose your stack direction before ordering – it determines how your curtains open and how the motor is installed.

Note: Centre opening motorised curtains require two motors – one for each panel.

5

Select Your Track & Brackets

Track Style:

072902-download-1

Sleek, square-profile design

072902-download-1

Puddled: approx. 20mm longer (sheers only)

Hem Style Options:

Blockouts:

072902-download-1

Overlocked hem (recommended to reduce flaring)

Sheers:

072902-download-1

Lead weight hem

072902-download-1

80mm sewn hem

Mike’s Tip:

An overlocked hem helps your blockout curtains fall cleanly and avoids flaring at the base.

7

Label Each Window

Start at your front door and move clockwise around your home. Label each window with its room name (e.g. Bedroom 1, Living Room) to stay organised during ordering.
