This is a common rangoli called bitter gourd rangoli as the shapes  resemble bitter gourds ( hagalakayi ) . Draw for Dhanurmasam .  We usually draw a lot of chukki rangolis during this month

  For a change the pics showing the steps in the reverse order :)  Invariably , Vaikasi Visakam falls on a Pournami like other festivals like Avani Avittam , Thai Poosam, Masi Magam etc.  Decorate this kolam with kavi or colours and beautify your house for the festival
