Tie-Dye refers to a method of producing colorful swirled patterns on cloth by tying it with string, rubberbands, etc. to shield parts of the fabric from the dye. Tie-dyed Clothing was popular with the counter-culture because it was home-made and individualistic, rather than commercial and mass-produced.
Author's Note: I remembered that my siblings and I together with my cousins and friends/neighbors made Tie-Dye from our old T-Shirts. I can not remember though exactly how old I was when we made this Tie-Dyed T-Shirts, I think during the 70's, the Hippie and Woodstock time. So in our subdivision, almost all of us had Tie-Dyed T-Shirts.
