Assemble
You will need:
Trash bags to protect working surfaces, plastic grocery bags to store your creations in, Paper Towels to clean up and wrap your work in, Rubber Bands to tie up your shirt with, Rubber Gloves to protect your hands, Eye protection, and clothing protection, Plastic Bucket to soak your shirt in, Chop Sticks to spiral shirts with, Dye squirt bottles, Dyes, Fixative, detergent, Clean Shirt, Or our tie dye kit :-)

Treat!
In the bucket, Soak in the right fixative, for the fiber reactive dye, that is a solution of one cup Soda Ash, or Sodium Carbonate in a gallon of water. Wring out the shirt really really well so that there will be space in the fabric for the dye.

Prepare!
Use only the right fabric for the dye you are using and follow the directions. I use a fiber reactive dye. So It won't react with synthetic fibers Nylon, Polyester, Spandex etc. But will work on any plant fiber based fabric, Cotton, Rayon, Hemp, Linen, bamboo, etc. Cover your work surfaces with plastic! Cover your hands with gloves eyes with glasses and wear an apron, or smock. Mix your dyes and fixative just before your tie dye session. Dyes don't keep well.

Step 1 spread out

Step 4 Crumple!

Starting in the center, bunch the fabric up little by little going towards the edges of the shirt. You want the folds to be as random as possible, and as similar in size as possible. slowly making the shirt a smaller and smaller circle or disk. When the entire shirt is as small as you can crumple it by hand, get out the rubber bands!

Step 3 Tie!

Using rubber bands, tightly band the crumple crossing the center like you cut a pizza! use as many rubber bands as you need. finding the parts along the edge that are pocking out and put on a band to pull it back in! try not to let any part fold over another part, you want a nice flat even disk.

Step 4 Dye!

Place your shirt onto a paper towel to absorb any extra dye or fixative on your working surface. A primary color is typically placed on the front covering the entire surface then the shirt is flipped and a secondary color is used to coat the back side. Of course you can place whatever color you want on your shirt. Random color, Random folds, Awesome! randomness!

On this sample, side 1 a heavy cover of yellow with a little primary red on top. Side two heavy cover of primary blue with a little primary red on top. colors blend in the middle giving all the rainbow colors on the shirt! Way Groovy man!

On this sample, side 1 a heavy cover of red. Side two heavy cover of dark blue. Not enough dye was used on either side to saturate the shirt enough to blend to purple

1.  Wait 24 hours!  The toughest part as you want to see your new creation!  Your Tie Dye needs to be kept from drying out, and left to sit for the dye’s chemical reaction to take place.  If you don’t wait a good 12+ hours the colors will not be as strong.  Waiting several days is just fine.
