I came across this blog post, "An RV Hobby That Pays." This couple has turned selling vintage jewelry into a viable business. Arlene finds old jewelry, repairs it, then sells it to antique dealers as well as directly to consumers in one of her two online stores.
As the business developed, they modified the RV to accommodate her jeweler's bench and storage cabinets. They now have a van to go jewelry hunting. The van serves as a "guest house" for company.They have both taken courses on jewelry repair and her husband on jewelry photography. Check out Arlene's sites at rubylane.com and rubyplaza.com.
