Berroco knit bits shows how to knit a button loop easily within minutes. 1) Thread a tapestry needle with a 18-24″ piece of yarn. 2) Knot the end of the yarn and insert the needle where you want your first button loop. 3) Make a second stitch an inch or so away from the first stitch. 4) Tighten up the thread, placing your fingers in between the yarn and the button band creating a loop. 5) Work blanket stitch around this loop, stacking each stitch on top of the previous one until the entire loop is covered with yarn.
