Confused with the pattern instruction by Kim Hargereaves

Hello! My name is Basia, and I’m new here. I would be grateful for Your help as I’m having a hard time interpreting this pattern. I’m working skimming tunic, and the pattern says this:

Row 37(RS): K3, K2tog,K to last sts, K2tog tbl, K3.

Working all decreases as set by last row, dec 1 st at each end of 8th and 4 foll 6th rows. 47 sts.

I started with 59 st cast on, What I dont understand is how am I dec 1 st if in the pattern there is 2st decreas, what is more what *th and 4 foll 6th rows means… :frowning: I know the abbreviations but do not understand what to do next.
PLEASE help me.

Hi and welcome!
The instructions are to decrease at each end of the row so that’s 2 decreases per decrease row.
Decrease on row 37 as shown in the pattern and then on rows 45, 51, 57, 63, and 67.
Enjoy finishing the skimming tunic.

Thank You very much. Now I understand!
Last dec row is 69 though, right?
Again, Thank You

Ah, thank you. You’re absolutely right. Last decrease row is 69.
