I have not done any ice dyeing all summer and it's something I really love to do. I have my dyed scarves in several shops and know they'll be calling me soon to get some more. I find this process works well in heat and heat we have - lots of - this summer, so before the fall takes over, time to finish up my supply of rayon scarves.
I did an experiment to satisfy my own curiosity to see the difference between using ice and this process and just batching with mx dyes. I used the same rayon scarves, the same mx dye colors - one was ice dyed and the other batched with mx dyes overnight - no ice. I think there is a big difference - the ice on the left and batching on right.
