The pattern is the Crocus Bud Shawl and I am making it with the dreamy alpaca-silk blend, Knit Picks Shimmer in the Cumulus colorway. The yarn is hand-painted in a subtle mix of grays--some lighter, some darker, a tint of brown here, a touch of icy blue there. I just love the resulting combination of the beautifully simple crochet pattern with this gorgeous yarn! I can't help but think of Mithril, of which Tolkien saud:
"[The shirt] was close-woven of many rings, as supple almost as linen, cold as ice, and harder than steel. It shone like moonlit silver."
Light and delicate, beautiful and subtle, all made into a clothe of many loops and chains. Thus the Mithril shawl.
(And don't you just love the corner of my arm the photo, as I attempted to stretch out the lace to show the pattern?)
