Long weekend knit cardigan

Im a beginning knitter and i want to make my first wearable piece. I found a free pattern by yarnspirations and i understood everything until the shaping of the shoulders.
It says to cont in pat, cast off 10 sts beg next 4 rows, then 9 sts beg following 4 rows. cast off rem 35 sts.
I would appreciate any help because i can’t seem to find any tutorial.

Ok. You are knitting a 4 row repeat, correct?

“Cont in pattern” - This means that you will continue knitting in the pattern u started earlier

“Cast off 10 sts beg next 4 rows” - this means that you will bind off 10 sts at the beginning of the next 4 rows (which you will be knitting according to the 4 row pattern)

“Then 9 sts beg next 4 rows” - this means that you will bind off 9 sts at the beginning of the next 4 rows (which u will also be knitting in that 4 row pattern)

“Cast off rem 35 sts” - this means that you will bind off the remaining 35 sts

Hope this helps
