Here are some pictures of fabric I discharged last week during Carol's class. For the first one a doormat was placed under the fabric - which was blue Kona - and than I used a foam roller to apply thickened thiox over it.
For both other pieces binder clips and rubber bands were used. The difference in pattern is because I fanfolded the fabric in a different way and probably placed the binder clips in a different fashion. The next step was to immerse the fabric into a thiox bath. Handdyed fabric discharged way quicker than commercial fabric does. After this bath I used different colors of Procion mx dyes.
