This yarn is the color Hyacinth in Liberty's Yarn. (Her blog is linked in the column to the right.)
It is a lovely smooshy soft superwash wool in a dk weight called D.Quixote yarn. You may have seen her work in the Dye for Glory competition.
The pattern is astoundingly well charted and I loved knitting a whole shawl in garter stitch, it is so lofty and textured and just all around wonderful. I think I will be knitting the Just Enough Ruffles scarf by Laura Chau with that lovely silk/wool BMFA yarn I got at Black Sheep Gathering. Don't ask me why I am knitting winter accessories in the middle of July, in a heat wave, because I don't know. (In fact I just finished that huge aran sweater, so that will be up next!)
