Seems like this approach to deco could translate easily to pots. Start with a simple cross as the starting point to a grid. Extend it out a bit with a series of dots to indicate the evenly spaced intersections. Experiment with joining them with a variety of curves and flourishes.
The fact that the source is a prayer, a meditation, an opportunity to welcome prosperity makes it all the more relevant to utilitarian pots for me.
Kolam is a form of sand painting that is drawn using rice powder by female members of the family in front of their home. It is widely practiced by Hindus in South India. A kolam is a sort of painted prayer - a line drawing composed of curved loops, drawn around a grid pattern of dots. Kolams are thought to bestow prosperity to homes.
