My LYS, Silver Creek Cabin, had a party on Halloween. What do knitters do on Halloween? Not trick or treat, not ghouly things or even bobbing for apples.
What we did do was knit and wear a bit of knitting on on our heads. Oh, we also had lots of good food too. Can't have a knitting party without food.
Little Bo Peep
Prairie woman and Raggedy Ann, I think.
A couple of improvised Hallowigs.
Skein Head? She won a prize.
Flower Girl or whatever, she also won a prize.
And that, my friends, is what knitters (or the ones I know) do for Halloween. Much better than the other options, right?
