Row 7: k3, p1, m1R, k3, m1L, *k3, p2 (repeat
from * to end of round)
Place a marker after the p1 and before the m1r, k3, m1l, pm, p2, work the rest of of the round in k3, p2. Knit the next round even; on following alternate rows inc between the markers. The thumbs appear to be worked in stockinette, your thumb stitches will interrupt the pattern, just pick it up again after the second marker.
