DIY Dyeing Jar – Tips & Ideas
The dye jar is a simple experiment.
The textiles have already been pre-treated.
The colors are derived from plants – e.g., from extracts, bark, flowers, or peels.
You will receive clear basic steps and inspiration – no fixed design templates.

What you need
– the glass or refill
– dye
– a textile that has already been mordanted
– Water from the tap
The basic steps (for all fibers)
-
Place the textile in the glass
-
Sprinkle in dye (Be creative here!)
-
Fill with tap water
-
Leave the glass standing
-
Finally, rinse and dry.
The differences lie in the water temperature and the standing time.


Cotton, linen, hemp
Water temperature: hot tap water (not boiling).
Standing time: from a few hours to several days, longer standing time = more intense color.
What is possible:
– Shake
– For a more even result, you can gently move the fabric in the glass, ideally with a spoon.
– Rubber bands can be used to tie off areas and create simple patterns.
– Do not place on the radiator
– Natural variation is part of the process
When to take it out?
If the color in the glass looks nice, you can leave the fabric in there a little longer.
After washing and drying, the color becomes slightly lighter – a longer standing time ensures that the color remains vibrant.
Iron:
After drying, you can iron cotton, linen and hemp normally (it doesn't fix, but smooths).
Wool (e.g. socks, hats)
Wool is sensitive to heat and friction.
Water temperature: warm from the tap (lukewarm).
Standing time: usually 1–2 days.
Important:
– Do not shake
– Move gently only once the fiber is completely covered
– No heat, no friction
– Do not place on the radiator
When to take it out?
With wool, you can also choose based on appearance, but only within the recommended standing time (approx. 1-2 days).
The color becomes slightly lighter after drying.
Iron:
Please do not iron wool. Heat can damage the fibers.


What happens while standing
– natural transitions
– subtle irregularities
– individual color development depending on the textile, dye, and resting
This variation is part of the project.
After dyeing
– Cotton: washable at 30 °C
– Wool: hand wash in cold/lukewarm water
– Slight lightening after the first wash is normal
What you get from us
– natural plant dyes
– a pre-treated textile (optional in the set)
– a glass or refill
– Inspiration instead of recipes
