And they made shirts for themselves. Here's how:
How to make tie dye shirts/stuff
wash and dry shirts with just detergent, no softner
A few hours before you plan to dye shirts soak them in soda ash for a couple hours. Soda ash is the same thing as arm and hammer super washing soda, you can get it at walmart in the cleaning section. 1 cup per gallon of water. This is what makes the dye really stick to the fabric and keeps the colors vibrant.
Wring out shirts and place in dryer on low heat for about 20 minutes or until shirts are damp. You don't want them completely dry.
Once your shirts are damp, fold as you want and you're ready to dye. We used a Tulip kit with a variety of colors.
After you dye your shirts, place them in a ziplock bag and let them set for at least 24 hours. You can let them set more if you want.
After the 24 hours is up, rinse your shirt under cold water for a few minutes, then remove rubber bands and continue rinsing until you get most of the loose dye out. Then toss in the washer on warm with detergent, dry as usual and you're ready to wear!
Wash separately for the next 2-3 times.
NOTE: Soda ash is great for neutralizing odors. I use it to soak dish cloths in before I toss them in the wash.
