Basically there are two ways you can do it; you can either pile the snow on the fabric then add the dye to the snow. This technique can get tricky if you don’t like muddy colors or earth tones because of the way the dye flows through the snow isn’t very controllable. If you want to keep the colors a bit more separated then make individual snow cones in bowls of one color to each bowl. Then place piles of colored snow on the fabric. This is the technique we used and we were very pleased with the results. We used I/2 yard and fat quarter cuts of fabric. I laid out all my fabrics next to each other and then piled on the colored snow. This created coordinating fabric because the fabrics contained similar colors.
