With the start of Makaram/Thai month, every thursday evening, our courtyards will be cleaned and adorned by kolam/rangoli. We put using rice/kola powder and rice paste. Some people change the kolams on monday evenings also. That is Tuesdays and Fridays will have fresh kolams made. I rarely change on tuesdays. But for Fridays it is always new kolam.
This is the start of the series for the month of kolam
