Right now, the smooth ‘v’ side is facing me, so that is the RS side, right?
You’re doing stockinette, so yes, that is the right side. When working on the right side, you knit. If you’re working flat, the WS is the side you purl on.
If the pattern stitch makes it difficult to remember (like seed stitch or ribbing) I put a locking marker on one side to remember. For me I always put it on the side I want to be the RS, but do what works for you. Then make a small pencil note on your pattern so you do t forget.
