It didn’t take long for the discharge paste to dry so I could steam my samples. My TUD instructions tell me to hover the iron over the fabric and I should see the colour fade. Once it is at the stage I like I should stop and then wash the remainder of the product out.
The dark grey cotton, commercially dyed, was much harder to activate and took longer to discharge. I didn’t let it go so far and could have done a bit more so the effect is stronger. On the green the powder resist is quite evident around the outer edges of the pattern but I’ve lost it completely on the grey. On the second grey sample I slowly swung the iron from side to side so the steam holes – aligned along the outer edges of the iron – moved laterally across the piece. Hence the discharge pattern.
So, not a bad result considering the TUD never really dissolved properly.
