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!
