Henna: Earthy Temporary Tattoo Set These deep red henna temporary tattoos are on the bolder side of the henna spectrum. They follow the custom of henna dye with their reddish-brown color. Use them as a visual aid for a discussion on other cultures in class, or grab a bundle for a cultural event at school. Have a henna tattooing day with a meaningful talk on its historical uses across cultures. Students can pick out a design that suits them, cut it out, and press it on with some water. They'll have a visual reminder of what they learned about other parts of the world that they can take with them.
