This shows the steps to draw a Celtic knot based on a central spiral taken from Celtic Knotwork designs by S Sturrock.

Two forms are given.

One is a normal knot with equal offsets either side of the centre line path.

The second is a ribbon knot where one side has an offset which is twice as big as the other relative to the centre line.
