[missjiggy23]

hi everyone

i have decided to attempt making some tie die tablecloths and selling them. however i would like to try and get hold of some plant dye, preferably organic if possible and some organic cotton, think these kind of products would appeal to some in a different way from normal tyes and materials. if anyone could point me in the right direction for getting some plant dye id aprpeciate it!!
