From the Signatur website:
Started from one Mitre square, stitches are picked up from one mitre to the next. Knitted from a diagram which shows the sequence in which to work the mitres, the legend gives the colour stripe per Mitre. The garter stitch makes picking up stitches very easy, picking up a stitch per ridge of the garter stitch. Knitted in a combination of 8 colours from wool, mohair and eyelash.
