There are detailed instructions on the internet. Basically prepare the fabric to accept the dye. Suspend some sort of screen over a container. Squish up the fabric, put on top of screen. Cover with as much snow as you can (tuck in any fabric peeking out) Using a powered dye(I use Procion Mx) sprinkle over the snow. I started with just navy blue, red, and yellow. The navy was always on the purple side. Which is why I need to try another blue dye. The most interesting results happened when I sprinkled one color and then came back randomly with another. Then you have to wait till the snow melts to see what happened. Then rinse and set the color.
