Although they knit up quick as a blink, the details are in all the right places for careful shaping to fit an average female adult hand perfectly. The purple / blue samples were knit with one 150g hank of Malabrigo Rasta. (At the 3 sts/inch gauge, I had about 5 feet of yarn left over from my one 150g / 90 yard hank. If you want to make the cuffs much longer, get a second hank of Rasta.) The magenta samples were knit with two 100g balls of Dale Hubro. Hubro is no longer made by Dale, but you can substitute with many different super-bulky wool yarns, as long as you can achieve the right gauge and have at least 90 yards of yarn.
