These mitts are graded for three sizes: S, M, L. Finished mitt circumference 7 (7.5, 8) inches /18 (19, 20.5) cm. They will also stretch comfortably.
You'll need 150 yds/137 m of fingering weight yarn for these mitts. I knit mine up in Knit Picks Stroll. Classic Elite Telluride is also a great option!
You will need scrap yarn for the thumb stitches, one stitch marker, and a tapestry needle. You will also need your preferred style of small circumference knitting needles. The suggested size is US 3/3.25mm
This pattern is good for intermediate knitters (or adventurous beginners). It uses increases, decreases, and twisted stitches, and the mitts are knit up in the round.
