u/anxietyintensifies

Hello, I am fairly new to knitting and after making a few beanies I am attempting to knit a sweater in the round. I have just finished the neck band and the pattern has asked to begin increasing stitches for the neckline. I am going from 68 stitches to 100 stitches. I understand how to increase but from what I understand the pattern only uses 36 of the original 68 stitches when increasing, what do I do with the remaining stitches in the row?

I am using the pine pullover pattern from knitting.tany.kim
