When I was still a child, I learned to draw Rangoli using a grid of dots placed equidistant from each other. It was fun!
At a later date, I discovered Karnataki Kashida , which also uses a grid for reference. The designs are made up using lines only.
After I started painting on walls, I had a brainwave. I used Kashida designs in a different way, using solid masses of colour. Here are a couple of results.
