Yarn: Plymouth Yarn’s Encore Colorspun worsted, last half of a skein used last year to make Mark’s Dashing Mitts.
Knit in the round on US size 8 circular needle.
I cast on 88 stitches and knit K2P2 rib until I got worried about running out of yarn, then decreased for the top till I had 8 stitches left. Then I knit i-cord for about 4 inches and wove the loose yarn through those 8 loops and drew it tight. I fed the end into the i-cord section and tied the i-cord into a knot on top.
The finished hat fits me as a beanie, so it should fit pretty much any other teen or adult. More terrible photos on blog post dated 11/16/10.
11/23/10 UTA: I gave this hat to my coworker Maresa for her 5-yr-old niece and hope to get a good picture of her wearing it soon. (Still waiting in March 2012.)
