There is a variation of dyes that we offer depending on the fabric.

Should you wish to have STSC manage a unique dyeing job for you then this is an additional Consultancy service to cover the time taken to do the job.

We will discuss with you your colour choices, decide on a method, order the fabrics, do colour testing on 1-3 metres per colour way, gain your approval, then proceed with full dye job.

Dyeing is a complex procedure when striving to make it as environmentally sustainable as possible and we believe that dyeing with plants is the most environmentally sound. 

Our plant dye mills are highly experienced and dye bulk lots and achieve the highest standards.  Clients must be aware that with plant dyes the outcomes are not always uniform and cannot be compared with no-fault chemical dyes and finishes therefore the fabrics may change after each wash - we like to think of it as giving you a new coloured garment even though the changes may be small and incremental over time.




Ayurvastra Fabrics – Natural, organic yarns are dyed by hand using plants that contain medicinal properties.

The dye bath infuses the fibers with the lovely natural colours of these plants, along with their healing components. The yarns are then woven into fabric, and made into clothing or bedding.
