I've used this yarn for many projects and the results are always beautiful. The alpaca is very soft with a little halo and the silk is just enough to give it some sheen, softness, and better stitch definition. This tends to be the yarn that I use the most for my lace weight projects.
I bought a hank of the yarn in the Cerulean color and started on the cuff of a sock while I watched TV. After I finished the cuff I put the knitting aside and noticed that my fingers are blue. I'm very concerned about what will happen when this yarn is washed but I am also not looking forward to the idea of having to scrub my hands every time I do any knitting. The yarn is nice and soft and knits up beautifully, though.
