You can Increase 1 stitch at each end every 3 rd row by knit 2 rows even. On the next row (3rd row), you increase 1 sts at the beginning of of a row and then work to the last stitch and increase another one. (when working increase at each end of a row like this, I prefer making an increase stitch just before the end stitch because it make the edge looks smoother).
"then increase 1 stitch each end every 6th row"
When you complete row 3, you start counting the next row as your 1st row because it's a new set of increase. You knit even for 5 row and then on the next row (6th row) you make 1 stitch increase at both ends.
Keep a row counter handy and reset a counter to 1 after each increase.
