Today I tried applying Procion dyes with a squirt bottle on silk. It was a handy way to get a mottled effect. My stand-by method comes from Ann Johnston's book, Color by Accident . I can't wait to see the results. These are the color groups I was trying to achieve and the dyes I used:
Bay Breezes (blue/turquoise)
Autumn Tundra (golden yellow/red)
Birch Bark (black)
Spruce Needle (blue/green)
Fireweed Meadow (fuchsia/iris)
Spring Birch (golden yellow/blue)
