The dot pattern is idukku pulli (i.e the first row of dots at the centre is drawn and the next rows on either side have dots between the dots in the central row and the next rows have dots between the previous dots and so on )as is show in the dot grid below.
In this rangoli the basic design is drawn with parallel lines to form a flower. Around the flower another parallel line border is drawn at some distance. Outside the border floral patterns formed with spiral and circular designs are drawn to decorate the rangoli. The flower inside has pink petals and the flowers outside have yellow petals. The gap between the border and flower has alternate blue and green lines.
Why does one need to know or practice many rangolis. Why do we need to combine the many motifs, designs in various combinations to arrive at new designs. Why would one need free hand designs and rangoli with dots. All these questions are answered when we know the philosophy behind the art of rangolis. Rangolis are drawn at the entrance of homes. The reasons attributed are many. One of them is that they are drawn to welcome guests. Since they are drawn with rice flour or rangoli powder or a mixture of both, at the end of the day the design drawn gets erased. Ephemeral is an adjective associated with rangoli quite often. It lasts for a very short time, only for one day. It cannot be preserved when drawn with rangoli or rice powder. Hence the necessity to draw new, newer rangolis. Obviously, repeating the same designs means the person who draws and those who view will lose interest. In such an art like rangoli novelty is welcome.
Hence the need to think of, practise and draw new and different types every day. It is practically not possible to draw rangolis in the literal sense (i.e with colours ) every day. Hence we usually draw plain designs
