Used 1mm carbonz to start but eventually ended up looser. Made .81mm needles out of music wire (works surprisingly well!) to finish second. Chart not entirely accurate in the end, need to update it.

swatch notes:

35 stitches, 52 rows in 4”, so about 9 stitches and 13 rows in 1”, so probably
72 stitches (27 stitches in thumb gusset, gusset takes 30 rows) around
140 stitches (or not more)
24-32 rows in cuff, 10-2 rows between cuff and thumb gusset start (64 from start to gusset end)
36 to decreases (100)
