On average, henna artists can expect to make $30-50 USD per hour. Simple designs may start at $5 USD, while more elaborate designs can cost upwards of $100 USD. Henna artists working at large events or festivals may also sell their services by the foot, with prices ranging from $15-30 USD per foot. However, earnings will vary depending on the artist's skill level, reputation, and location. Artists working in busy tourist areas or affluent neighborhoods can often charge higher rates than those working in smaller towns or rural areas. Henna artists typically work on a freelance basis, so their income may fluctuate from month to month.
