    How to measure

    Measure the width and height of your window carefully before ordering. Check whether your product uses an inside or outside mount, and review all measurements before checkout because custom-made sizes may not be returnable.

    Made to order

    Your window treatment is prepared to the size and options selected on this page. Colour and texture can vary slightly between screens and natural material batches.

    Shipping & returns

    Production and delivery timing depends on the selected product and destination. Please review the store shipping and return policies before placing a custom order.

    Before you order

    Made-to-measure, made clear.

    How should I measure before ordering?

    Measure the exact width and height more than once, then confirm whether the product requires an inside or outside mount. Custom orders are produced from the specifications submitted at checkout.

    Does the no-drill option require tools?

    No-drill products are designed for tool-free installation on compatible window frames. Frame depth, trim, handles, and other obstructions can affect suitability, so contact us if your window is unusual.

    Is the shade cordless?

    Products identified as cordless are raised and lowered using the bottom rail, giving the window a cleaner finish without dangling operating cords.

    What level of light control should I expect?

    Light-filtering materials soften daylight and add privacy, while blackout options provide stronger room darkening. Performance varies by material, lining, colour, and surrounding light.

    Why can natural material colours vary?

    Bamboo, jute, linen, and other natural materials can vary slightly in colour, texture, and weave. These individual characteristics are expected and make each treatment distinctive.

    What should I know about custom-order returns?

    Made-to-measure products may not qualify for standard returns. Review the selected material, mount, width, height, and other options carefully before ordering, and contact our team if you need help.
