Here are the samples from my last immersion dye class. The participants were fourth level students at Gail Harker's Center for Creative Studies (www.gailcreativestudies.com) and a wonderful group of women. I thoroughly enjoyed meeting and working with them. The results were puzzling though. I couldn't get the madder to go red and the cochineal wasn't anything like the tests I ran at home (red yarns on top were dyed at home, and the two sets beneath came from the class). We used more fibers in more forms than I usually work with in a class... two weights of wool thread, silk thread, silk organdy and linen... but I don't think that made the difference. I'm wondering what could have caused the change. I used a 2% ferrous sulfate afterbath on the chocolate brown and it came out so dark that indigo hardly changed it. Next time I'll go back to a 1% bath so there is more of a difference.
