Wallpaper - Hay Blue

Our Hay Blue wallpaper, designed by Becky Thorns, brings together soft sea green linear brushwork across an airy, off-white background. Arranged in alternating horizontal and vertical blocks, the painterly ink strokes create an engaging geometric rhythm that feels both structured and effortlessly relaxed. The subtle variations along the edges of each line give the surface a gentle, hand-drawn look, while the muted palette keeps the overall atmosphere peaceful and grounded. Produced made-to-measure on our PVC-free paper with a subtle surface structure, it is straightforward to hang and adds an understated, contemporary presence to any interior.

In the room

We particularly like this design in spaces where you want visual interest without overwhelming the room. In a home office or study, the alternating horizontal and vertical lines create an orderly yet soft backdrop behind a desk or shelving unit. The pattern also works remarkably well in hallways and staircases, where the geometric direction helps guide the eye through transitions and across tall or narrow wall sections. Because the contrast is gentle, you can easily use it across multiple walls without the pattern feeling crowded, though it equally shines as a focal point on a single wall with natural daylight highlighting the soft sea green tones.

Styling it

For styling, we recommend leaning into a clean, Scandinavian aesthetic with functional, well-proportioned furniture. Pale timber pieces, such as natural ash, birch, or light oak, complement the organic feel of the brushstrokes, while simple painted furniture in matte neutral tones helps the subtle green lines stand out. To maintain balance, pair the wallpaper with unpatterned, softly woven upholstery and simple architectural shapes that allow the linear geometry on the wall to remain the central decorative feature.

Colour combinations

The wallpaper is composed of muted sea green ink lines set against a light, neutral off-white ground. Around the room, we suggest introducing soft sage, warm stone, or pale grey on adjacent walls, woodwork, and skirting to keep the space seamless and harmonious. If you prefer a touch of contrast, deeper muted greens, slate, or rich dark wood accents will pick up the cooler undertones of the linework and provide a subtle, elegant anchor to the surrounding decor.
