OK, there are two posibilities.
Yes, I see what you mean about the end of working yarn. You've just finished knit row. (1)You can break the yarn, leaving about a 6 inch tail to weave in later. You can put those 8sts from the right heel onto a holder or another needle so that you can slide them onto a working needle to begin a knit row at the other end with a new strand of yarn.
(2)The only other way to get going again is to purl back on the 8sts, turn and start the directions that follow for knitting 8sts, picking up 9sts etc.
