This pattern shows you how to knit these handwarmers in the round, no seaming, using the Magic Loop method.

I’ve not yet found a hand they didn’t fit.

These handwarmers are made to stretch a little when you put them on, so gauge is not a huge deal - knit some 2x2 ribbing in the round with different sized needles to find a fabric density that you like. ~2.5 mm needles are recommended to start with for 4-ply/fingering weight yarn.
