This time with the Cookie A Sock Club pattern I went by the book and actually used the club yarn, Dream in Color Everlasting Sock in the Violet Hour colorway, because I felt it was the perfect choice for the Tulip Socks pattern. The yarn is a bit splitty, but with this pattern it was manageable, and the socks are so soft. This is an example of a yarn that I probably would not have bought were I to pick something up from a yarn store, but the color grew on me during the knitting process, and I enjoy the very slight color variation (that is not evident in the photos).
