Garter Stitch: Is there a Wrong Side?

I am making a baby sweater and the first piece; the back; is knit every row. The pattern says to knit 9" and end on a WS row. Is there a wrong side row when doing garter stitch?

Both sides are the same in appearance. The only reason why I could see a garter pattern having a wrong or right side is possibly for the appearance of the cast on, but that’s just a guess.

Thank you! This is the first item I have attempted that has to be pieced together and I am a bit nervous about it!

Congratulations on your impending arrival! If you need any further help, someone is always happy to step in.
