One way of doing screen prints is to use discharge paste or thiox in stead of paint/dye. On this black piece of fabric (H200 from Whaley) I started with discharge paste. After ironing it, the fern leave only showed up as a pale ghost. I had no idea how old my discharge paste was, so I screen printed again using fresh made thiox paste. Well, the result was the same. This fabric discharges to white using bleach, but it gives very little result with discharge paste or thiox.
I had to change which material to use, cause I still wanted to work with this fabric. This time I used Setacolor white opaque and a white shimmer and again the same fern leaves:
