Custom River blackout curtains in a linen-polyester blend that combines the organic warmth of linen with complete room darkening performance.
The River Stonewall Blackout Curtain is where natural texture meets high-performance room darkening. Woven from 96% Polyester and 4% Linen, this 344 GSM curtain carries the organic, tactile surface of linen while offering the durability, washability, and light-blocking capability of a premium polyester construction. The flowing cool blue-grey suits interiors that value material honesty --- Japandi, Coastal, Transitional, or any space where a natural finish makes the room feel considered and calm.
Made to your exact measurements, the River Stonewall panels hang with a beautifully relaxed weight and a surface texture that looks intentional from across the room. Custom sizing ensures perfect proportions for any window.
The Stonewall collection accommodates:
Japandi and Scandi-inspired interiors that value natural texture and calm neutrals
Coastal and organic-modern spaces where linen finishes feel at home
Bedrooms and living rooms that want blackout performance with a natural aesthetic
Transitional interiors that bridge contemporary and classic design
Spaces where flat, shiny synthetics feel out of place
Anyone who wants the warmth of linen with the ease of a washable polyester blend

Fabric Information
The River Stonewall is woven from 96% Polyester and 4% Linen --- a blend that captures the organic, textured surface character of linen while retaining the practical benefits of a performance polyester. The linen content gives the fabric its distinctive slightly irregular, stone-like texture and a warmth that flat synthetics cannot replicate. At 344 GSM, it hangs with a relaxed, weighted composure. Despite its natural-looking surface, it is a full blackout curtain: light block is built into the fabric structure rather than applied as a separate coating, ensuring consistent performance across the whole panel. Tested to 45,000 Martindale rubs, it is durable enough for everyday use in bedrooms and living rooms alike. Machine wash at 40°C, line dry, and low iron if required.
Integrated blackout construction --- no separate backing layer
45,000 Martindale rub test --- durable for everyday use in living rooms and bedrooms
Machine washable at 40°C --- all the appeal of linen with none of the delicate upkeep
Low iron if needed
Multiple top type options --- Grommet, Tab Top, Rod Pocket, Sleeve Top
Available in 12 coordinating colourways across the Stonewall range
Frequently Asked Questions
Both River and Haze are cool blue-greys, but they occupy different tonal positions. River is a flowing, mid-tone blue-grey with more presence than the lighter, mistier quality of Haze. River is slightly richer and more saturated — it reads as a confident colour choice rather than a subtle background tone.
Yes. The blue-grey of River creates a beautiful visual connection with garden greenery — cool blue-grey against lush green is a classic nature-referenced pairing. With the curtains open, the colour dialogue between interior and garden is harmonious.
140 cm is the panel width. For flat coverage, you need 2 panels (two 140 cm panels give 280 cm, sufficient to cover 240 cm). For a gathered look at 1.5x fullness, you would need 3 panels (3 x 140 cm = 420 cm, divided by 240 cm gives 1.75x fullness — approaching the 2x target).
Yes. The Sleeve Top or Eyelet (Grommet) options are compatible with track systems. For pinch pleat or pencil pleat header styles, you may wish to enquire about additional header options. Contact us for guidance on matching your preferred track system.
Textured fabrics can hold pet hair more readily than smooth surfaces. The Stonewall's organic weave is a slight pet hair attractor compared to a flat synthetic. Light vacuuming or using a lint roller regularly will keep the fabric surface clean.
River sits between those two references — not as warm or turquoise as duck egg, and not as dark or cool as slate. It is a mid-position flowing blue-grey, which is what gives it versatility across both cool contemporary and softer, more organic interior schemes.
We strongly recommend ordering a fabric sample before placing a made-to-order purchase. Colour and texture can look different in your specific lighting and alongside your specific furnishings. Sample availability can be confirmed on the product page.
South-facing windows receive the most intense UV exposure. To protect the fabric, consider using a sheer or light-filtering blind on the inner face of the window to diffuse direct sun when the curtains are open. Keep the curtains in the open position as much as possible to limit sustained UV exposure on the face.
We recommend the Stonewall for bedroom and living area use rather than bathrooms. High moisture and steam exposure in bathrooms is not suited to this fabric. For bathroom windows, a moisture-resistant roller blind or specialist bathroom curtain fabric would be more appropriate.
Yes. The panels are supplied with finished hems as part of the manufacturing process. The hem finish is clean and appropriate for the fabric. You do not need to hem or finish the curtains yourself.
