I used a little more than one 50 gram ball of Knitpicks Gloss for these gloves. To be precise, they required 56 grams. You would have enough left to make some fingerless mitts with the rest of the second ball.

Errata: Little finger of right hand should read, “Knit across 32 stitches of stockinet section. Place last 12 stitches of stockinet and next 4 stitches (first four stitches of the chart) on two needles.”
