Help with sleeve on rowan pattern!

Hi I’m currently Knitting my boyfriend a jump and have just started on the sleeves now but have confused on this section.

Start with 37 sts.
Beg with a K row, work in st st, shaping sides by inc 1 st at each end of 3rd and 1 foll 4th row, then on every foll 6th row until there are 61 sts.

Does this mean: K row, P row, K row(increasing either end), P row( increasing row). then carrying on increasing on every 3rd and 6th row or just on the 6th rows?

Can anyone help please???

Thank you

No, the first inc row will be the 3rd row, and inc on the 4th row [I]after[/I] that, then on the 6th rows after that one which will all be RS rows. So it’s rows 3, 7, 13, 19, 25 etc.

Thank you that’s greats, I can now carry on. I just find the patterns confusing sometimes.

Patterns will be written like this, you kind of have to break them down step by step which may make them easier to read and understand -
inc 1 st at each end of 3rd row
1 foll 4th row, then
every foll 6th row until there are 61 sts.
