Here it goes. You'll need an H hook and some leftover worsted weight yarn.
To begin the hat, you can either use the magic ring method (click here for a how-t0) or ch 3 and then ss in the first stitch to make a loop.
Rd 1: sc 6 times in the loop (6)
Rd 2: sc twice in each st (12)
Rd 3: sc one in the first st, sc two in the next - repeat 5 times (18)
Rd 4: sc one in each st (18)
Rd 5-12: Repeat rd 4 (18)
Fasten off.
For the hanger just take a piece of scrap yarn, pull up through the top and tie into a loop. Double knot for extra strength.
To add on decorations you can put ear flaps like mine, or a bobble or you can put in stripes in the middle. These little guys can be easily customized into the perfect gift. Also, they double as beer bottle hats! Sweet!
