So I made one for myself out of a different fiber. I used Debbie Bliss "Party Angel" which is a much thinner yarn and that's why I double stranded it. I made it exactly 50 rows longer so I can wear it as a cardigan and I used a size US7 needle instead of the US8 to get to the same gauge. I love the result!
And there are many other manufacturers producing a similar yarn: Rowan "Kidsilk Haze", Cascade Yarns "Kid Seta Noir", Schulana "Kid Seta" and I am sure there are many more.
