Fun with Ink
Few parents would allow their children to get a permanent tattoo, but many of them see no harm in allowing them to get their face painted or a temporary tattoo at a fair or festival. This art pieces are generally designed by practicing artists, and face painting is generally a skill many artists learn to enhance their income. It is a harmless way to entertain children, and many artists have a great time when attending these types of events.
Tattoos are very permanent unless drastic measures are taken, but the temporary transfer tattoos and face paint at fairs comes off easily. Many of the inks and paints are vegetable dyes that can be washed off without too much effort, and face painting is generally a type of water color. The fact that these items are temporary is part of the fun, and this is one of the reasons that parents are amenable to allowing their children the fun of experiencing them.
