The math is not working out for me which means I'm interpreting something wrongly.
I'm shaping the arm hole on the back side of the vest and I have 100 stitches on the needles, the instructions call for "At the beginning of next two rows, BO 6 sts." My interpretation: I'm on a right side row so I bind off 6 sts. knit to end then turn and bind the first 6 sts in purl since I'm on a wrong side row. Then, "Decrease 1 st each side this row, then every other row 3 times." My intrepretation: On right side I k2tog knit accross to the last two stitches and k2tog, turn and purl back on wrong side, turn and k2tog knit accross to the last two stitches and k2tog and repeat this two more times. I now have 80 sts on the needles but the instructions say I should have 76. What am I not seeing?
