I read this article on the growing popularity of the homemade cookie business:

Of course, many of these home businesses bake cookies that make the standard chocolate chip cookie look like health food. People want a special treat and reason that it is "just one."
I'm amazed at the cookie decorators, as I would think that much decorating would be very hard on the hands. (I'm saving my hands for stitching.) I'm sure that they charge a justifiably premium price for their creations.
