By the Rosalinda Ontwerp Design Team · Pretoria & Garden Route
There is a moment — when a room finally comes together — that every interior designer lives for. The light falls at the right angle, the fabric catches the air, and the space transforms from simply furnished to genuinely beautiful. In our 40 years of bespoke curtain-making and interior design at Rosalinda Ontwerp, few window treatments create that moment as consistently as wave curtains.
Whether you are designing a light-filled home in Waterkloof, a coastal retreat in Knysna or Plettenberg Bay, or a boutique guesthouse along the Garden Route, wave curtains offer something increasingly rare in interior design: a treatment that is simultaneously timeless and contemporary, effortlessly elegant and entirely practical.
In this guide, our qualified designers walk you through everything you need to know — from how wave curtains work, to choosing the right fabric for South Africa’s diverse light conditions, to the installation details that separate a good result from a flawless one.
Wave curtains are defined by their continuous, uniform ripple — a soft, flowing S-curve that runs from the track to the floor without interruption. Unlike pinch-pleat or pencil-pleat curtains, there are no gathering points and no stiff folds. The fabric moves in one seamless, rhythmic wave.
This is not achieved by chance. The wave effect is engineered through a purpose-built curtain track system with evenly spaced gliders that are pre-set to a fixed interval — typically 60 to 80 mm apart — so the fabric is held at precise, consistent points across the full width of the window. The result is a drape that looks deliberate, architectural, and calm.
This characteristic makes wave curtains a natural fit for the interiors we work with most often at Rosalinda: warm minimalism, biophilic design, and the relaxed luxury aesthetic that defines the best contemporary South African homes.
The track is not an afterthought — it is the foundation of the entire look. At Rosalinda Ontwerp, every wave curtain track is custom-made to the precise measurements of your window or opening. We do not use off-the-shelf solutions. The quality of the track determines the quality of the drape, and the quality of the drape determines the quality of the room.
Two installation configurations suit different architectural contexts:
Fabric selection is where the expertise of a trained designer becomes invaluable. South Africa’s light is not European light. It is stronger, more direct, and — particularly along the Garden Route — coloured by salt air and the particular brilliance of coastal mornings. The fabric you choose must work with that light, not against it.
At Rosalinda Ontwerp, we carry an extensive library of international and local textile brands. Here is how we guide our clients through fabric choices for wave curtains:
Sheer and Semi-Sheer Fabrics
For Garden Route holiday homes, coastal properties, and Pretoria rooms that face a beautiful garden or view, sheer wave curtains are transformative. Voile, linen sheers, and fine polyesters allow the full quality of South African light to filter into the room in a soft, diffused way — eliminating glare without eliminating the view. Unlined sheer wave curtains create a sense of space and airiness that is particularly suited to the biophilic and nature-connected interiors our clients increasingly request.
Linen and Linen Blends
Linen is the defining fabric of the contemporary South African interior — and with good reason. Its natural texture, its relaxed ease, and its quiet sophistication make it the ideal fabric for wave curtains in both residential and hospitality settings. Linen drapes beautifully, holds the wave form with natural confidence, and ages gracefully. Our linen selection includes European and South African woven linens in a range of weights, from lightweight sheers to medium-weight lined options for enhanced privacy.
Velvet and Heavier Weaves
For Pretoria bedrooms, private studies, media rooms, and hospitality spaces where deep light control and acoustic comfort are priorities, we recommend lined velvet or heavier woven fabrics. When correctly manufactured and installed, these fabrics hold the wave form magnificently — the weight of the fabric actually enhances the drape — while providing superior insulation and a sense of warmth and luxury that lighter fabrics cannot match.
Patterned Fabrics
Wave curtains are one of the best possible showcases for patterned fabric. Because there are no gathered pleats, the pattern flows across the window uninterrupted — you see the full repeat as the designer intended. Botanical prints, abstract weaves, and large-scale geometric patterns are all beautifully suited to the wave format. This is a detail that matters particularly when working with the premium international fabric brands we stock — their pattern repeats deserve to be seen in full.
The decision to line or not line your wave curtains is both aesthetic and practical, and the right answer depends on the room, the climate, and your priorities.
Accurate measurement is where the difference between a good curtain and a perfect curtain is made. Our designers carry out all measurements personally for projects we install — but if you are planning in advance, here is what you need to know:
Some of the most spectacular wave curtain installations we have completed at Rosalinda Ontwerp have been in commercial and hospitality settings. The format is exceptionally well-suited to environments where a consistent, polished aesthetic must be maintained across multiple rooms or large open spaces.
For boutique hotels and guesthouses along the Garden Route — a market we serve extensively — wave curtains solve a common challenge: how to achieve a high-end look across many rooms without the variation that characterises hand-crafted gathered curtains. The engineered precision of the wave system means each room is identical, the brand aesthetic is upheld, and guests experience a consistent quality of finish.
For corporate offices, boardrooms, and co-working spaces in Pretoria, wave curtains in neutral linens or subtle weaves create environments that are calm, focused, and visually refined — precisely the qualities that the current evidence base around workplace design links to staff performance and client perception.
One of the practical advantages of wave curtains is how straightforward they are to maintain. The absence of deep, complex pleats means dust has fewer places to settle, and regular upkeep is simple.
Our design team works with clients across Pretoria and the Garden Route — from initial consultation and fabric selection through to custom manufacturing and professional installation. Every project is handled with the same personal attention to detail that has defined Rosalinda Ontwerp since 1982.
