From the Knit Picks Website:
Gloves are not difficult to knit. They’re just unwieldy. So many needles! Instead, try knitting with one circular needle (Magic Loop) and with the help of another circular needle and two dps for the finger set ups. Directions for both fingerless mittens and fingerless gloves are included.

Sizes:
Women’s sizes - 4.25 inches across back of hand
Uses fingering weight yarn
Men’s sizes - 4.75 inches across back of hand
Uses sport weight yarn

You will need 1 skein of fingering weight yarn for women’s and teen’s sizes plus about 30 yards of a contrasting color. For larger size, 2 skeins of sports weight yarn and 30 yards of contrasting color.
