Natural Dye Studio
Color from plants & food waste. We dedicate ourselves to the art of ecological dyeing. Workshops • Research • Design
MACHWERK EXHIBITION 26.10 - 31.10
For the "Off Duty" collection, we work exclusively with B-grade goods and discarded textiles. We re-dye and redesign them using walnut shells, chestnut, and avocado pits.
WORKSHOPS
A studio, real botanical dyes.
Our open sessions are introductory workshops for anyone who wants to work with their hands—no prior knowledge or preparation required. You show up, we get started. Whether it's adding color with bundle-dyeing, going blue with indigo and shibori, or a kids' workshop: new formats are added constantly. Sessions with more time and depth are currently being planned.
PRIVATE EVENTS
The cosmaki studio is exclusively yours. You will dye together, work with your hands, and take home something that cannot be bought anywhere else.
We offer private sessions for groups, children's birthday parties, team events, and brand activations – featuring bundle dye, indigo shibori, and more. Whether for a bachelorette party, birthday, family reunion, or team day: we take care of everything. You just need to show up.

THE NETTLE COLLECTION
The secret in the weed. A plant most people throw away. We have produced a small capsule collection from it. Printing technique: Cyanotype. Limited quantities
NETTLE
RELEASE 16.08.
Where the color comes from
At the end of May, we cut the first nettles from an allotment garden in the neighborhood. A plant that most people treat as a weed. What could be dyed from it was also an open question for us at the beginning: extracted, set, discarded again, until the color was right.
On August 16, a small t-shirt collection made from it will be released. Natural dye is just the beginning. The rest remains our secret until then.
Online from August 16th.
The Nettle Collection
Naturally dyed, in a small edition. Sold out means gone. Until next year, when we can harvest again.
Newsletter subscribers receive early access and a small handmade giveaway.

cosmaki is a natural dye studio located at the machwerkhaus in Cologne-Kalk. We dye textiles using real plants and make the process accessible through open workshops and private sessions.
Our formats: bundle dyeing, indigo and shibori dyeing, kids' workshops for ages 4 and up, and exclusive team events for groups of 6 or more. All workshops take place at the cosmaki studio in the Machwerkhaus, Dillenburger Str. 91 in Cologne-Kalk.
For companies, we offer creative team-building events and brand activations in Cologne and the surrounding area – using genuine natural dyes, no prior knowledge required, with lasting results.
We upcycle hotel textiles and old fabrics by giving them new life through natural dyeing – stains become part of the pattern, and no two pieces look the same. A service for hotels that take sustainability seriously.
