I rejoined Quiltart as a lurker, and many of them are doing some snow dyeing this winter. I feel like a sheeple, but I have a little fresh snow this week. :-|
I used two colors of dye, "Royal Blue" and "Raspberry". The latter separated into component colors very quickly:
The concept is that as the snow melts, the dye will seep onto the fabric, creating interesting patterns--especially if, as I have done, you have used a dye mixed from two or more separate colors.
My results? I don't have them yet. After four hours only half the snow has melted. :-\ Stay tuned.
