15st in thumb gusset (2 extra st, 3 more rows)
length = 30 rows

Thumb: change to #4 p 6 rows. Diameter too large. Next time, stick with 13 st. But, 1 more row btwn increase rows. (3 rows btwn increase rows)
Palm: can be a few stitches wider. Maybe CO 40 next time?

My hand measurements:

Wrist: 6”
Palm: 7”
Thumb: 2.25”
Length from thumb gusset to tip of middle finger: 4.5”
