I made these for my daughter's co-worker. She's been really nice to my daughter so I'm gifting them to her.
I combined patterns. For the CO number and basic idea I used this the 220 Fingerless Mitts found on Ravelry. For the thumbs I followed Cabled Fingerless. Yarn is Plymouth Encore Worsted #194 and US size 6 and two circs. Cable CO and k2tog bind off for stretchiness.
