Gauge isn’t that important on these unless you knit incredibly tight/loose. These are perfect for those tempting almost warm days when mornings are cold but afternoons are hot. Just pull these on over your favorite heels and keep you legs and tops of you feet warm. These allow your heel to pop through while protecting you feet tops to still be covered. Use whatever worsted weight yarn you desire close to your skin. I choose Cascade 220 because of it’s color selection, yardage, and value. 1 skein will make shorter version, while 2 skeins will give you the longer version.
