If she would be interested in starting it as a cottage industry, and then marketing from a successful start toward the mass market/manufacturers, CarolC had a recent thread about marketing her artwork. Not specifically fot textiles, but maybe relevant about doing it from home.

I had friends who were wonderful artists and made a nice living designing molds for table service-- potters who had day jobs designing hospital trays, plates, cutlery, etc. They always talked about how heartbreaking it was to deal with the employer-employee feature when it came to art from their hearts. I've experienced that as well, writing ad/promotional copy in a commercial setting when what I love to do is write grant proposals for projects I believe in.
