Make a foundation of evenly-spaced Straight Stitches. Thread two blunt (tapesty) needles with contrasting colors. Bring both threads up at A. Weave one thread under the first straight stitch and weave the second thread under the second straight stitch. Cross the first needle over the second so that it is now on the top. Now weave the first needle under the third straight stitch. Repeat all the way down the band. Repeat the same pattern from A until the band is as wide as you want it.
