How To: Natural Tie Dye
- Cotton T-Shirt (organic cotton or bust)
- Yellow onion skins and/or coffee grounds (two of the best natural dyes)
- Rubber bands
- A non-reactive pot (stainless steel or enamel work well)
- Iron mordant (optional) **
- Put a handful of rusty nails in a jar.
- Fill jar with 2 parts water + 1 part white vinegar.
- Cover and set aside until the solution turns orangey (1-2 weeks).
To dye your clothes:
1.Throw your tees in the wash with a pH neutral detergent (most "sensitive skin" detergents fit the bill). When they're nice and clean, soak them in a pot of water for at least an hour, but ideally overnight.
2. Meanwhile, put your dye supplies (coffee grounds or onion skins) in a non-reactive pot, adding just enough water to cover your shirts. Bring the water to a boil and simmer (for at least an hour, but overnight if you can). For this project, I used about 10 onions worth of skin for one shirt and a half gallon bag of used coffee grounds for a second shirt (1 shirt per dye pot). It's possible to continue dyeing with the dye pots until the color is "exhausted" (aka producing really, really light colors). You can also adjust the amount of natural ingredients to get your colors darker or lighter.
3. After your shirts have soaked, you can bind them into tie dye patterns.
5. If you're using an iron mordant, now's the time. Simmer 1 cup of your iron solution with water for 30 minutes (make sure you use enough water so that your shirts will be fully covered once you submerge them). Remove the solution from heat and dip or submerge your shirts - iron works quickly so this may only take a few minutes. Rinse out.
6. Hang to dry in a shady spot, then wash your shirts with a pH neutral detergent again.
7. Get excited to wear your new naturally dyed tees!
**A few safety notes: As a general rule, it's best not to use any pots or utensils for food after they've been used for dyeing. If using an iron mordant, keep solution out of reach of children and pets; avoid breathing steam from an iron bath and simmer in a well-ventilated area. Iron mordant can be safely disposed of down the drain in municipal areas. Once you've gotten this technique down, it's easy to learn how to make natural dyes from plants and other food scraps—and the world is your oyster when it comes to things to dye. Think pillowcases, dish towels, cloth for wrapping gifts (a favorite sustainable trick—get instructions here). When sustainability meets creativity, everyone wins.
