I also dye a lot of my own fabrics and use Kona cotton but I have been buying it from Dharma trading where I also buy my Procion dyes and other supplies like the Synthrapol. I have a lot of different colors and usually dye gradations of 6 or 8 of each color when I do it. I will have to get the black as I have found that that is a hard color to find sometimes and I seem to use a lot of black in my projects.I bought a book on ebay and that is how I started. I have never tried snow dyeing but it looks interesting. We get lots of snow here usually so I might try that this winter. I have tried sun printing and my 6 year old grandson loved helping with it and seeing the results of the items he put on the fabric.
