Tie-dye

How can I tie dye a spiral pattern into a bandana? What chemicals do I need?

It depends what colour you want the tie-dye to be. White is the easiest because all you need is simple household bleach, rubber bands and disposable gloves. Or if you want a different effect, use bleach in a spray bottle and spray it straight onto the material from a small distance in the bath. Works really well with t-shirts too!
