Hi, I am a new knitter and am attempting to follow a pattern for the first time. I've just done 25 cm of stocking stitch and I'm supposed to end on a right side row. What does that mean?
Thanks

The right side also means the front side, which in stockinette would be the side where the stitches look like Vs.
The wrong side, also called the back side, would look like little bars in stockinette stitch.

Finish the RS knit row, then the next instruction will be for the WS purl row.
