I have this pile of wacky chartreuse wool that I bought on a whim a few weeks ago, but what do you do with yarn like that?? Make a wurm, apparently (it's free as a Ravelry download). This is such a fun hat - and a nice break to all the lace I've been knitting lately. Just rows of knit and rows of purl, alternating to form the wormy segments. I think it'll be a fun addition to my knitted accessories basket. Might have to make mitts to go with it...mitts with stripes...oooh! Please, don't get me started!
