Pattern: Cable Hat Book: Just Hats from Lion Brand Materials: Knit Picks Swish Worsted 100% Superwash Merino Wool Amount: 3 'Capri' Needles: US6 bamboo Cost: Cardigan - at $3.29/ball approx. $9.87 I made this hat last year in an adult size but the yarn I used was not quite thick enough I guess so it turned out a bit on the small side. This year, my 3-year old was able to wear it. Much to my surprise, the pom poms are still attached.
