My pattern reads:
work in reverse stocking st, shaping side seams by dec 1 st at each end of 7th and foll 12th row. Work 11 rows, end with a RS facing for next row. Inc 1 st at each end of next and foll 10th row.
Does this mean to decrease at row 7 & 12 OR row 7 & 19.. i would then assume that the increases would be at row 23 or 31 & at 33 or 41 based on how the patter is actually read!
sorry this is a bit confusing for me! darn european patterns..
