Clown Kids make great clowns and can hire themselves out to birthday parties, senior citizen groups, nursing homes, and other community gatherings. Also a great opportunity for younger kids birthday parties and small community fairs. This makes a great business for two kids to do together. One child can do the face while the other does the tattoos. Popular also are washable hair sprays in bright colors.
Kids can spray stripes, stars, rainbow designs, etc., onto hair of young customers.
Markets include selling designs to magazines, finished products at craft shows, church bazaars, etc. Do not overlook original ideas along this line either, as one mother told me of her oldest child who drew original comics in the third grade. If your family has a garden each year that provides tons more than your family ever uses, trade gardening help with your child for the excess produce. This is not a new idea, but still a good one, especially if you live in an area or neighborhood that has pet owning couples, and both work outside the home. Make sure to meet with both pet owner and pet beforehand, so that you know your child will be capable of handling the animal.
