Wallpaper - Botanical Blue Lines

Created by Katie Pertiet, our Botanical Blue Lines wallpaper brings a relaxed, hand-painted feel to classic vertical stripes. The design features soft, watercolor-like bands of cornflower and periwinkle blue set against a crisp white ground, defined by delicate, fluid outlines that give each stripe subtle movement and variation. This balanced visual rhythm creates an open, tranquil atmosphere across the wall without feeling rigid or overly formal. Like all our wallpapers, this design is made-to-measure to your exact dimensions on PVC-free paper with a subtle surface texture.

In the room

The vertical orientation and airy spacing of the stripes make this pattern especially effective in transitional spaces. In a hallway or along a staircase, the vertical lines draw the eye upward and bring a sense of height and continuity. We also see this working beautifully across all four walls of a powder room or bathroom, where the rhythmic blue stripes create a fresh, tailored look that feels cohesive in compact proportions. Because the watercolor tones vary naturally within each stripe, the pattern remains gentle and easy to live with across multiple walls.

Styling it

We would lean into heritage, cottage, or classic coastal styling with this design, pairing the crisp blue and white palette with painted millwork, traditional wainscoting, or beadboard.

To keep the room feeling balanced, we recommend pairing the wallpaper with simple, clean-lined furnishings and soft ceramic accents rather than competing patterns. Warm white painted trim or muted navy details help anchor the space, while unlacquered brass or polished nickel fixtures provide a timeless, refined finish that complements the watercolor style.

Colour combinations

The design is built on soft shades of cornflower, lavender-blue, and indigo alongside clean, soft white. When choosing surrounding colours, we suggest crisp off-white or soft ivory for adjoining walls and trim to let the blue stripes stand out cleanly. For a richer contrast, deeper navy or dusty French blue on a vanity, interior door, or painted furniture pieces will naturally pull from the darker pigments within the painted lines.
