It's at this site: http://knitting.about.com/gi/dynamic...vil%5fhat.html
It hangs below the earflap of the hat. Here's the pattern instruction:
Devil tail ends: Cast on 1 stitch at either side of I-cord (5 sts). Knit 2 rows, reduce 1 stitch each end (3 sts). Knit 2 rows, k2 tog, k1, turn, k2 tog (1 st). Break off yarn. Draw end through last stitch, pull firmly, Draw end up through I-cord to hide. Repeat for other side.
Thanks for any help!
