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.
Business can offer one or both services.
Bathing pets is a service often overlooked as too difficult for kids, and many pets may be too hard for kids to bathe easily and safely. Often though, an older person may own a small breed dog that just needs a bath now and then, and the owner can no longer get down on his or her knees comfortably and do the job themselves. Summer time, kids may handle larger dogs by offering one afternoon a week to wash the pets outside. Have them offer their services as a tutor to younger children. Teachers may even be able to suggest possible clients.
