I'm not too clear on this part of the pattern:
Read all of the following section before knitting it!
Work in stockinette sts back and forth on needle, at the same time dec 1 st each side on every other row a total of 2-2-2 (3-4) times.
AT THE SAME TIME inc 1 st on both sides of marker mid back on every other row a total of 4-4-4 (5-5) times.
After all inc and dec are complete there are 58-62-64 (72-76) sts on row.
When piece measures 11-12-13 (14-15) cm / 4 3/8''-4¾''-5 1/8'' (5½''-6'') inc 1 st each side towards mid front on every other row 4-4-4 (5-5) times.
At the same time I dec at each side, I inc in the middle for every row? Or, dec at each side, inc in the middle for one row, then stockinette the next row? Or, dec at each side every other row, then inc the middle every other row without dec?...I'm so confused here.
