Mobius Shawl cast on

For those of you that do not know what a mobius strip looks like, you can see examples here. Basically it is a complete circle with a single twist in it. In knitting a mobius you have two knitting needles attached by a long cord or wire, the right needle is in the front, a left needle goes around, down, up to the left so that you have 2 loops but they should only overlap once. What this does is cause a continuous pattern so that you are knitting both sides of the shawl at once. You use a marker for the beginning of the row and it is so cool to see the marker move under the area you are working on the lower wire and then come around to the needles again.
