knitting Pattern

Although I can knit I have great trouble interpreting patterns (I have ADHD).
I am knitting a collar for a doll’s school polo shirt.
Ist row is rib
Next row k1,p to end,K1
Next row k
then you have to repeat these rows
Then it says cast off 5 sts at beginning of next 4 rows Do I cast off while following the above rows or do I just do it in rib?
Any help much appreciated, thanks

Hi Patsy, I am not the biggest expert, but yes, you would cast off in the pattern you are currently working. I hope this helps, good luck!

Welcome to KH!
What is then name of the pattern you’re following? Can you give us a link?
