get a plain white vest/shirt/dress/piece of material, old or new

if youre only making one shirt,dont make the full amount of dye
i used an empty ice cream container for each colour

part 1
roll it up,starting at the bottom right corner and ending at the left sleeve

part 2
use string or elastic bands to tie rolled up shirt into as many patritions as you like,as far or near apart as you like
(i tied 7 partitions because i wanted to do a rainbow.the 1st being the smallest and each partition gradually got larger)

tip - you can tie the string tighter

dip your first partition in your 1st colour
dont forget to wear gloves!

holding your other colours out of the way,dip in your next colour until the string on either side of the partition is touching the dye

continue in this way till all your partitions have been dyed

cut the strings and hang up your garment to dry on a coat hanger
