Our clothing is made from high-quality organic cotton – soft, durable and comfortable to wear.
Depending on the style, the cut can be classic, loose, or fitted. Fabric weights vary between 155 and 350 g/m².
All pieces are pre-washed, pre-treated and dimensionally stable.
After dyeing, please wash separately, preferably at 30–40°C using ecological detergent.
We use aluminum triformate – a gentle cold stain that ensures that plant dyes adhere better and shine permanently.
Our blanks come from Stanley/Stella , a pioneer for sustainable textiles in Europe.
The pieces are made from certified organic cotton, are fairly produced and durable – ideal for your DIY project or your label.
We source the goods directly, prepare them in our studio and package them plastic-free.
This keeps the supply chain short – and you know where your product comes from.

Stained – what does that actually mean?
In order for plant dyes to adhere permanently to textiles, preparation is sometimes required – the so-called mordant.
Cosmaki offers you two options:
- Unmordified: Ideal for indigo or if you want to mordant yourself
- Stained: Prepared with a cold stain, ready to dye directly for madder, onion skin, avocado, cutch & Co.
You don’t have to know everything – we’re happy to help you choose the right one.
