A mitten to hold your beer and a mitten for the other hand with a side thumb.
You will need 1 skein of your main color and 1 of your 2nd color, double pointed needles sizes 4.5 and 6 (US 7 and 10), 2 stitch markers, 2 safety pins and a tapestry needle.
I use Álafoss wool but you can use any yarn with similar gauge (made for needles 5.5-6.5 mm)
