Without chukki rangoli for daily use

I do not use any aids viz.  drawing the pattern with chalk piece , using scale to get perfect symmetry.  Whatever symmetry I attain is through practice only.  Use the white rangoli for daily purpose 

Same small and easy rangoli with colours for Diwali 

I hope you will agree that the rangoli drawn above is reasonably symmetric.  This design can be used as the central part of a bigger rangoli .  We can start with this and then expand.  As a matter of fact the flower design is most commonly used. 

 Here there are 16 petals .  We can have 8 or 32 petals too.  Optimum number is 16, for drawing 32 we should use the thin line technique.  What ever the number the gaps have to be filled with some simple patterns.
