And the Moon ? To find the South direction is also possible to use the shadow of a vertical gnomon produced by the moon. The coordinates of the Moon are easily found, in winter the Moon is very high and the shadow is well visible. I have tried in my kitchen last night: the shadow of my hand against the refrigerator was very clear and well contrasted :-)
