I tried Rayon, Rayon lawn, Polyester shantung, haboti. and two different weight cottons.
What I ended up doing was wasting a lot of paint
Way too much wicking and even without the wicking I wasn't getting the soft colors I was trying to achieve.
Stopped before I wasted even more paint on this one
Then I tried some painted fusible web. I'll iron this on various colors and white and see how it shakes out.
Back to the drawing board
