You can also hold it together with the working yarn for a few stitches- that will weave it in while you work, so you won't have to do it later. You just have to remember that each of those stitches will have 2 strands of yarn, so when you work them again later you have to knit (or purl) the 2 strands together, otherwise you'll end up with more stitches than you started with.
