Lanterns market during Diwali is dominated by Chinese products, however those products are not eco friendly. That also does not support the Make in India Initiative. For the last 2 years, I have been making my Lanterns at home. I use paper and all material which is available easily. This is also not much time consuming.
This year, I made the Lantern with paper, and a simple colour plate. Cones which you see are made with papers and they are stringed together.
I wish you all a happy and safe Diwali. Cheers.
