Traditional indigo dyeing transforms light-colored textiles into various shades of blue. The color develops during the dyeing process and becomes more intense with each dip. Our medium-strength dye bath enables classic indigo tones of medium intensity. Each piece receives its own, natural color depth.
Indigo dyeing is a natural, water-saving process. The traditional dyeing process does not use harmful chemicals and creates long-lasting textiles that improve over time.
FAQ
Can I dye multiple items?
Yes. Each textile requires its own dye ticket. Maximum three tickets per person.
Do the textiles need to be freshly washed?
Yes. Please bring only freshly washed textiles without fabric softener . Residues from use or care can prevent the indigo from being absorbed evenly.
Can I arrive later or leave earlier?
Yes. Please allow approximately 60–90 minutes per textile.
What happens if my result is different than expected?
Indigo is a natural dye – results are unpredictable. That's precisely what makes the process so special.
Can I dye synthetic fabrics?
No. Only natural fibers are dyed.
Is this suitable for beginners?
Yes. We will guide you through the process; no prior knowledge is necessary.
What happens if my part is not suitable?
We reserve the right not to dye unsuitable textiles.
