I bought this as a kit at the CreativFestival in Toronto last October. The pattern is by Stephen West and it was included with the yarn - Noro Silk Garden Sock yarn, color S241 and Ella Rae Lace Merino, color 8. You can see the pattern here.
I wet the starting end and "blocked" it (laid it on a towel and patted it to the shape I wanted) to see if it would look different. You can't see the change in the photo, but it drapes much nicer and doesn't look as lumpy where the yarn changes from the Noro to the merino.
