KnitPicks is my favoritefavorite online yarn shop. They have such beautiful and reasonably priced sock yarn, and their pattern selection is awesome.
Last winter, on a whim, I ordered the yarn to make this "Day at the Beach" sweater. I finally cast in on last night, and I am totally in love. It's going to take me FOREVER to knit this thing, but it will be very pretty once it's done!
I'll have progress pictures soon. Once I have more than two inches of herringbone done!
