Question about K2 P2 Rib

I noticed that when I do a k2 p2 rib for the sleeves of a cardigan that I’m doing that it ended up with the last 2 being purl and then i start the next row and the purl from before was knitted. now i picked up 54 stitches for another part of the cardigan and it begins and ends with knit. will the rib come out the same if not how do i pick up 2 additional stitches without having to go back and do it again or can i just simply add 2 stitches somewhere in the middle so it won’t be noticeable.

For a 2x2 rib to be knit the same on both rows, you need a stitch number divisible by 4, which 54 is not. You’ve found that the back of a purl is a knit and so the back of a knit is a purl as well. So if it ends with a k2, you begin the next row p 2. Learn what your stitches look like and when you do ribbing you always k the knit sts and purl the purl sts [B]on the new row[/B]. Always however they look on the row you’re working on, not how you made them the row before.
