Hi everyone. I am a new member with a question

I am knitting my grandson a sweater. The pattern is four rows. I am knitting the sleeves. How do you increase on a row at each end while maintaining the continuity of the pattern? I always have a problem with this.

Welcome!

When you’re increasing on a sleeve, think of it expanding outward.

You can kfb in the first and last stitch for the first increase, and when you get to them on the next row, treat them as if the pattern widened. For example, if you were working a

.kkppkkppkkppkk rib, expanding would give you
pkkppkkppkkppkkp until the next increase.

If it’s a more complicated pattern, just work the stitches in stockinette until you have enough to work the pattern stitches.
