This fabric was dry painted – using a brush that had been cut irregularly to produce a more random edge with most of the dye shaken off, it was brushed across the fabric repeatedly, using different colours and shades. I like the texture produced when it picked up various folds and wrinkles in the fabric. The first photo is a detailed shot of the second.
I can see this fabric being useful for landscape backgrounds and suchlike.
This very interesting piece of cloth is actually the fabric I used to wipe the dye from the plastic used for one of my experiments! I think the black was thickened dye paint and the greeny colour unthickened but it turned out quite dramatic!
