Twist your bedding fabric in one of two different ways, yielding either one continuous spiral, or several rings spread out across your fabric. To make one spiral, grab a handful of fabric and start twisting until the entire thing is twisted nicely into a ball. Secure it with rubber bands. To make several rings, twist the fabric a few separate times. Then secure it with rubber bands.
Lay down newspaper over your entire work surface before you being dyeing. Overestimate the amount of space you will need, because any stray dye will permanently stain.
Prepare your dyes in large buckets. Depending on the type of dye you purchased, you will have to prepare it in several different ways. Read the instructions carefully and wear protective gloves, so that your skin does not absorb any dye.
Place your dyes on the newspaper in order from lightest to darkest in color. To begin dyeing, start with the lightest color first, and check to see how long you must wait for your dye to set, before you start dipping into the second color. Also note that any overlapping in color will result in a mixture of those colors, so if you start with yellow then dip into red, your overlap will become orange.
Repeat steps one through four for the rest of your bedding pieces, until your set is complete. Clean up your workspace immediately after you have finished dyeing, using hot soapy water. Hang dry your new tie-dyed bedding.
