Just a word of caution - I love to dye fabrics but am not able to mix the dyes due to having asthma. Dharma folks said it was not safe even if I wore a respirator mask. Solution-found some ladies locally who like to hold classes and they have the dyes premixed for everyone along with the soda ash. So I always have fabric ready and when they notify me they are holding a class, I pay the fee, skip the classroom (with their permission) and head straight to the dying room! Wonderful for me. So suggestion is that if you have a respiratory problem, maybe you can find someone to mix the dyes for you!
