We bought a tie dye kit and tie dyed t shirts. First we soaked the shirts in an unknown solution that was in the kit, then we twirled the shirts and rubber banded them into 7 different sections..  Lastly, we applied different dye colors in each section.  We let them dry over night and then put them in the dryer to seal the colors. After the colors were sealed we unwrapped.   VOILA!!! you now have a tie dyed shirt !!!!!!
