This one is 100% Baby Alpaca called Peru. I used acid milling dyes, as I did on Mackenzie Blue, which is 80% merino and 20% bamboo, and also on Chopsticks . Vine is Blue Faced Leicester with 25% nylon. The next one, Winter Holiday, I dyed using Kool Aid. I almost binned this because I thought it looked awful but once it was cooked, it became this. I am glad I waited.
