These mitts are designed to fit a woman’s hand. Because the gauge is relatively loose, the mitt is quite stretchy and would fit a variety of hands. There are two options provided for sizing the length of the thumb.
Sizing may be adjusted by changing needle size (larger needle=looser fit) or by adjusting the number of cast-on stitches by adding/subtracting stitches in sets of 7. Please note that increasing the size of the mitts will use more yarn.
