Repairing unraveled beginnning rows

I know this is a weird question, but I don’t have a lot of experience knitting. After I finished a knitting shrug, I accidently unraveled the first 3 rows and I can’t figure out how to knit them again so they will come out looking the same. It’s a knit 2 purl2 ribbing and I’m trying to reknit them from the beginning. Is there a way to knit backwards or something? Does this make sense?
Thanks, ymorgan

You can put the stitches back on your knitting and reknit in the other direction, but the stitches will be reversed. If it’s only three rows, though, a good bet would be to bind off the stitches there and both ends will match–even better than having a cast on and bound off edge. They’ll both be bound off.

Thank you. I will try that. The sleeve ribbing will just be a little narrower.
It’s wonderful to find a forum like this. Thanks, again.
