When unsure, sweets, fruit, or flowers (avoiding white ones) are safe defaults. Skip leather items unless you know the recipient doesn’t observe the custom, and steer clear of frangipani or white flowers specifically, which are used at funerals.
If you’re giving cash, the amount matters more than you’d expect: a round number ending in zero (₹1,000, ₹2,000) reads as incomplete or even inauspicious, since zero signals an ending. The custom is to add one rupee, ₹1,001 or ₹2,001, so the gift symbolically keeps growing rather than closing out.
Hand the gift over with your right hand or both hands. It’s common for the recipient to set it aside unopened rather than unwrap it in front of you, that’s polite restraint, not disinterest.
