It appears to be way too big for a little kid, so I'm not sure what to do with it. Maybe I will bring it to Thanksgiving dinner tomorrow and consult my sister and brother-in-law.
(sanspoof, this is some of the yarn you gave me.)
I used this pattern. Er, I just now noticed that there's a worsted weight version of the pattern. Whoops, that would have been good to notice sooner! Actually, it looks like that would knit up really quick, so maybe I will use the rest of the yellow yarn to make one in that size -- I think I might have enough.
