This is traditional lamp arrangement done with a kuthuvilakku on festivals. it is called nalvilakku and the lamp can be either lit or not and fully decorated with manjal, kumkum and flowers. I have done this using a marron plate for the base with sambangi, chrysanthemums, oleander and nanthiavattai.
Karthigai Kolams
This was done using rice batter on karthigai deepam festival. A regular traditional kolam with lamps arranged on it.
