If you can sew, there is demand for alterations. As hand crafts of all sorts make a come-back, this is one opportunity you might not have thought of.
My local sew-er just told me she is swamped with business, always. People bring all sorts of clothing needing a hem, or sleeves shortened, or holes patched, to the dry cleaners. The cleaners hand the jobs over to her. She does no marketing, and has more demand than she can handle, from a town of 5000 people.
