Used size 6 needles to cast on and for first row of ribbing (K2, P1). Used size 4 for rest of mitten.

Carried yarn in back for chart portion. Made penguin on top and PENS inside palm for left mitten and the opposite for right mitten.

Thumb needed 18 rounds to reach desired length.

Note for the future - Secure ends in ribbing very carefully. I didn’t weave in the ends well enough for ribbing on right mitten and because of the stretching of that area, two ends came loose, making holes. Knotted those together and reinforced with another piece of yarn to close up tightly.
