Before you do anything, wash your fabric. Seriously. New clothes have a chemical coating called sizing that repels dye like a cat repels water. Old clothes have sweat, dead skin, and mysterious stains. Yum.
Wash it in hot water with a little detergent. No fabric softener—that’s like greasing the slide for your dye. You want the fabric naked and ready for its color transformation.
The Wet Cloth Rule
Here’s a pro tip that sounds insane: dye your fabric wet. A dry piece of fabric absorbs dye unevenly, like a sponge soaking up a milkshake. A wet fabric lets the dye swim in smoothly.
Don’t wring it out like a chicken neck. Just let it drip a little. We’re making art, not laundry.
