The pattern panels on the backs of the hands are typical of panels found on traditional stockings. The thumb gusset comes out of the palm rather than the side of the mitts, to prevent the pattern from skewing. The stitch pattern on the palm and thumb gusset is one often used as a filler stitch for calf gussets, and is also incorporated into more complex stitch patterns, much like seed stitch and moss stitch are used in Aran patterns.
