I played with discharge dyeing last month.
I used Avlyn Creation's Nature Palette

"100% Cotton Naturally Dyed fabric. The dyes we use come from plants, vegetables, minerals and some animal products. All are non-toxic, non-allergenic and completely biodegradable and environmentally friendly"
They didn't even have to be scoured!
This was my first foray into discharge dyeing, and they are not very artistic, but it was fun. I used dishwasher gel and rubber stamps, my hands, free form designs.
This could become addictive! See the details:
