When I designed the Snowy Penguin Vest I had enough yarn to knit up a matching set of mitts and a hat. I am so excited that this set is my first ebook!
A note on yardage: The samples were knit entirely out of 2 balls of Cascade 220 Superwash (Purple – 101 g, 222 yards with 1 g remaining; White – 87 g, 192 yards). The colorwork patterns in the hat and mitts were knit with the colors inverted to keep the entire set to two balls of yarn. If you are worried about yardage, I recommend knitting the ribbed brim of the hat in C1 (CO + 5 ribbed rounds) and switching to C2 as the MC for the chart.
