It is easier to do than explain. But with my Fiber Trends pattern it tells you at one point to mark the front of your knitting with a marker. I did that.
So when knitting on the RS the marker faces me, when I turn my knitting, I am knitting on the wrong side (no marker, the marker is on the back side)
You don't need to turn it inside out, just turn the whole thing a half turn in your hands. (when you get to the part where your are knitting on the RS and purling on the WS, it will be easier to see, but that is why they have you put a marker on the RS of your work to help you.)
I am not good at exlpaining this I am sure. Someone else will come along with the magic words that will click for you.
