We also are waiting for the arrival of Adirondack Color Wash which can be used on fabric, paper and other fibers. Here's what I was playing with on the piece of fabric below.
The Lettuce Green was put on while for fabric was totally dry and a wet paintbrush was used to move around the color. The Stream color on the bottom was applied to the fabric after it was wet. Then a wet paintbrush was used to fill in the white portions.
Then I used the Color Wash on a canvas. I applied the color and let it dry. Then I applied the 7 Gypsies tissue paper, coming soon, over the top. Now to add some dimensional bits to it.
