Connect the dots to get curved lines without a break. This is the important tip in this rangoli
Colourful lines are better than filling completely for this kolam
This is one of the most awesome rangoli designs you can draw for Diwali

The more you observe your elders drawing kolam, the easier it is to learn. This is my experience. When I draw for my videos, my daughter observes me occasionally as she is busy with her own avocation during holidays. I asked to draw a rangoli on the surface I draw for my video shoots. She took the kolapodi and drew a beautiful design in a jiffy. The lines were beautiful and thin.
I asked her to try a double line kolam. Immediately she drew parallel lines quite easily. We should remember that children always observe us. They learn both positive and negative things from us. So, we have to be careful.
On a lighter side, my husband who shoots the videos for the past ten years, tried a rangoli a couple of times. He could not manage even one line. He gave up and said, "I will restrict myself to shooting videos henceforth."
