It is generally advisable to schedule the bridal mehndi on a separate day from the sangeet, ensuring that it is completed before any large gatherings. For instance, if numerous family members are expected to arrive in the evening, it is best to have the henna/mehndi applied in the morning. This approach allows for a more intimate setting, surrounded by only a few close individuals, which can facilitate a more relaxed atmosphere and ensure that the design process is efficient and yields the best possible results.
