Booking mehendi for the bride is a design problem. Booking mehendi for 20 guests at a sangeet or haldi function is a logistics problem - and it needs a different plan. Estimate timing realistically. One artist can typically do simple party mehendi (5-10 minutes per person) for about 20-25 people in a 3-hour window. If you're expecting more guests, or want more detailed designs, book multiple artists rather than stretching one person too thin - guests waiting an hour in line rarely enjoy the experience. Confirm designs will be simple by default. Group/guest mehendi is meant to be quick and pretty, not bridal-level intricate. Set that expectation with your artist(s) upfront so nobody spends 20 minutes per guest and creates a bottleneck. Set up a proper station. A dedicated table, good lighting, and a visible queue system (even a simple sign-up sheet) keeps things moving. Chaotic "everyone crowd around" setups slow artists down significantly. Ask about a team booking rate. Many artists offer a discounted per-person rate for group bookings above a certain headcount, since it's guaranteed volume for a fixed time slot - worth asking about directly rather than assuming it's not available. Plan the queue by event flow, not fixed timing. At a sangeet or haldi, guests move in and out constantly - having the mehendi station open through the whole function (rather than a fixed 1-hour slot) usually works better than forcing everyone to line up at once. And don't forget drying time - dense guest queues often forget that wet mehendi needs 15-20 minutes before it can be touched. Have a designated "drying area" with chairs so guests aren't smudging their own hands rushing back into the crowd.
