On behalf of Sunayna..
There is a local NGO based in mumbai that is trying to raise funds through selling diya’s
I am a volunteer with the organization – Touching lives. I have an initiative called “Art with Sunayna” I make earrings, greeting cards, coasters, frames and other products from upcycled paper.
Every year, Art with Sunayna conducts diya sale to raise funds for the ngo – the complete profit goes to the ngo.
