This top is knit from Panda Silk (Fern Tones) by Crystal Palace, and is 52% Bamboo, 43% Superwash Merino, and 5% Combed Silk. Which is to say, it knits beautifully, feels wonderful to the skin, and can be hand-washed. I used a pattern from Knit One Below by Elise Duvekot, which creates a softly draping fabric with little to no curl. There was no need for blocking.
I was concerned about the sizing, but it fits just fine. On the other hand, these photos are reminding me that I really need to to hit the gym.
