I shook bottles of ProChem Designer colors (liquid) onto a piece of fabric to make sprinkles.
These are brush marks with a paint brush. I saw a beautiful embroidered piece with one long brush mark of paint with multiple small stitches along the top. Very effective.
This fabric was colored by wiping off my paint brushes and wiping up paint. It isn't finished yet but I love the intense color and random patterning. This would make a fabulous background.
