Baby cardigan sleeve help!
The later.
On the 5th row, then every 6th row (11, 17, 23 …).
On the 5th row, then every 6th row [I]after[/I] that. So on rows 5, 11, 17, etc.
I know the numbers seem odd to you. There’s a reason for that. They want you to make these increases on the right side rows. It’s just easier to increase on right side/knit rows than on the wrong side/purl rows. The increase intervals will give you graduated, even increases so the sleeve is shaped better.
