On row 1 of pattern says work through the center point between holes in lace at each end.
Row 3 of the tutu, reads k16 tlpy. After you do the turn do you complete the row
Row 8 again a lacing row, but this one reads, cut lace carefully. Thru centre of last hole, as before.
When the pattern of 12 rows is complete, you have to knit an extra row as the lace is done on wrong side if you don't. Totally confused.
