I didn't want all the fuss of dyeing, I wasn't in the mood for all the effort involved in that, so just tore up a few small pieces of white cotton, and had some fun.
I spread the paint onto a flat plastic tray, and then made marks into it with a variety of objects. I used some of the cotton fabric dry, and some I dampened down. With the piece on the left here, I placed elastic bands down onto the paint first, and then pressed the fabric down on top. When it was dry, I used silk paint to fill in the white areas.
