Arvind Bhargava, owner of Sundram Cards, also works on the basis of themes.
"Sometimes, brides want cards that match their lehengas and the decor of the venue. Once, someone wanted a lotus theme. We created a box in the shape of the flower. The card inside it looked like a leaf," he said.
As far as various cultures are concerned, colours and designs remain same but the symbol of the god changes.
"Hindus mostly go for Radha-Krishna designs, the Waheguru symbol is popular among Sikhs, Christians like church or couple-themed designs," Bhargava elaborated.
