Design and Development: Hand-Knitted Garments Brought to Life
The Heart of Our Work
Every garment begins with a conversation. Designers show us different forms of inspiration: some provide full technical packs (which by the way we often do not need), others bring sketches, reference photos, or a vintage piece they would like to reinterpret. Whatever form the idea arrives in, it is translated into the specific language of handknitting.
This translation is what sets KOCO apart. Most designers do not have experience with handknitting techniques. Guidance, information and support is provided on what is possible, with clear explanations of how stitch choice and yarn type will impact the design. When KOCO and the designer begin a project, everyone discusses the details clearly at the start such as the design idea, yarn, size range, timeline, and what is technically possible.
Because these things are agreed at the beginning, there are no surprises or confusion later. Both KOCO and the designer understand the same plan for how the garment will be developed, knitted, and finished.
The process is inherently sustainable. Because garments are made entirely by hand, they require no electricity, no industrial washing, and no chemical finishing. The environmental impact of production is minimal. This is not stated as a marketing claim, but as a natural result of how handknitting works. When a garment is knitted by hand, it does not require power, machines, or any water or chemical finishing after it is made. The knitters work in buildings with natural light. Garments are made completely by hand and finished by hand. The only energy involved is human energy.
From Sketch to Swatch
Once the concept is clear, swatching begins. A swatch is a hand-knitted piece of fabric that shows how yarn, tension, and stitch pattern combine. This step is essential because it allows both designer and knitter to see how the garment will behave before moving into full sampling. It can reveal whether a stitch has the right drape, whether a yarn feels too heavy or light, or whether any adjustments are needed.
A stitch library of more than 300 examples is available on our website, ranging from knit and purl textures through to lace, cables, and colourwork. Designers can begin by browsing existing swatches or request a custom adaptation. If there is uncertainty about the best choice, recommendations are made and test samples knitted to compare side by side. This process ensures the fabric chosen is not only visually striking but also practical for the garment type, avoiding costly surprises later.
Material choice at this stage also shapes the garment’s environmental footprint. The type of yarn used in a garment has the greatest influence on its total carbon emissions. At KOCO, almost all work is done with natural fibres. Designers typically choose wools, cottons, mohairs, or silks. These materials come from nature and can return to nature at the end of their life. They are renewable and, when untreated, biodegradable.
In the fashion industry as a whole, most emissions come from synthetic fibres such as polyester and acrylic. These fibres are made from oil and gas. Making one kilogram of polyester fibre produces between nine and fifteen kilograms of carbon dioxide. Even a small amount of polyester changes the environmental picture. In many machine-knitted garments, polyester thread is used for seams and hems. This thread usually weighs between fifteen and twenty grams in a jumper but can add about a quarter of a kilogram of carbon emissions to each garment. A KOCO jumper does not contain polyester thread or synthetic additions. Our seams are sewn from the same yarn used in the garment.
When natural fibres such as wool, cotton, silk, or mohair are chosen, and combined with KOCO’s low-impact making process, the total emissions of garments remain very small. This is what happens with every KOCO project: the process is built around simple, practical actions that keep energy use close to zero and materials as pure as possible.
