Errata: There is an error in Round 17 that only affects the smallest size.
Row 17 should read:
Hand of mitten
Round 17 (RS): Change to larger hook, ch 1, 1 sc into each of the next 2 (0, 2) sts, [2 sc into next st, 1 sc into each of the next 3 (4, 4) sts] 8 times, 1 sc into each of the next 2 (0, 2) sts, join with a sl st to the 1st sc of round -44 (48, 52) sts.

Description These mittens are thin enough to keep in your coat pockets, but thanks to a dense stitch pattern, they keep the winter wind out and your hands warm. The long color changes in this yarn create the stripes, allowing you to concentrate on the stitch pattern.

Gauge 25 sts and 17 rows = 4” in star st patt on larger hook; 24 sts and 24 rows = 4” in rib patt worked in the rnd with
smaller hook.

Notions St marker (m); yarn needle.
