I usually use a crochet hook, as well. But a tapestry needle will work just as well. you can even knit every stitch with the tail already cut (a few inches long) and then pull the yarn through with the free end of that loop.
so: knit the stitch (no other stitches on the right needle), then pull your right needle away from your knitting to elongate the stitch you have until it snaps out with the free end. Do the same thing with the next stitch and so on.
I mainly use that for very few stitches or when I do not have other tools at hand (on the train, when I do not want to dig through my bag or anything). More work than crochet hook or tapestry needle, but less tools.
