My yarn and needlework santa sent me a skein of lovely hand dyed yarn.

I'm a bit embarrassed. I was hoping to have already had the perfect project in mind for it by now, but I'm honestly stumped. I've looked though dozens of patterns and nothing feels perfect yet.

If anyone knows something great to crochet with 420 yards (1), let me know. I'm hoping to make some sort of accessory (but I want something that can be made in one piece. Something that doesn't need to be cut; I don't want to break up that great variation look in the yarn).
