Okay. It says:
With the RS of your sweater facing you and a separate skein of A at WS of front, pu the center sts between safety pins by *inserting the RH needle into the center of the next st from front to back, wrapping the yarn as if to k, and pulling the loop through.
I tried this already, but ended up with the yarn on the back and my needle on the front. How do I do it? I don't really know how to explain what I don't understand about it.
