Open Doors have placed partners in the country to teach women the skill in schools, free of charge.
Rebecca Coatsworth from the charity told Premier about the people they want to help.
"Women in India who become Christians find themselves quite often rejected by their family, by their communities because of their faith," she said during Premier's News Hour.
The sewing schools have been set up in remote villages in central India. After graduating from the school, most of the ladies are able to earn a living by working in tailor shops.
Coatsworth shared a success story about a 36-year-old mother called Deepa, who converted from Hinduism to Christianity.
Deepa, whose name has been changed for security reasons, told the charity: "Our teacher taught us very well. I can stitch professionally. Now I stitch blouses and salwar suits for ladies using the machine."
She said her conversion made her family and village turn on her.
"I was extremely disheartened," she said.
"Many times I even considered returning to my old faith."
Coatsworth explained how much the workshops help women.
"These sewing workshops are not only teaching them the skills that they need to earn a living and also run their own businesses, but they're also being strengthened spiritually through prayer and through mentoring from the teachers at the workshops," she added.
