This rangoli is a simple but striking design. The white elements of the design are made with dessicated coconut, which just shows what a little creativity can do!
In some areas of India, rangoli are made only with white powder, relying on their design for impact. This lovely design certainly has impact! The powder lines are made by dropping the powder through the fingers in a sort of pinching movement.
