Oh lovely,Is it created in your house or else where?
This was created in Mr.Ram's driveway (in California). He contacted me through ikolam a few years ago, asking for a kolam/rangoli based design. And I designed a few samples. He chose the design that had diyas in it. You can read the entire sequence/post here:
