Q&A for How to Set Tie Dye

You can hand-wash them with hot soapy water and dry outside for a few hours.

Always wash with salt in the washing water. It helps the color stay.

Wash new colors in cold water until you're sure the colors have 'set'. Some fabrics and manufactured dyes take longer than others-- more than several washes. Also, be careful to wash colored clothing with colored clothing.

Not unless they are all the same color. If they aren't all the same color, then the colors could bleed onto other shirts. And even if they are all the same color, you might not want to risk any color bleeding.

Try tie dying with the same color of the words so it isn't noticeable. If they're black, this isn't the best idea, as it doesn't look the best, but if you really don't want it visible, you can tie dye it a bit black.
