One other thought: Is there a way you can advertise your knit stuff at work--a bulletin board or a company Web site that has a community-based venue? Or maybe a company arts and crafts fair?
You might could even post ads on other bulletin boards around your community (grocery stores and community centers are two places that often have public and free bulletin boards). Right now, of course, many people are looking for Christmas gifts, and handmade items are so worth the money (as long as it's worth it to you to make them, that is).
