I agree with @RioVistaAndy about the 'home made' thing. I just say "I build furniture" and leave it at that. If asked what kind of furniture I build, I just say "I build Modern - Contemporary, mostly custom. I have a nice shop" and just leave it at that. That leaves the conversation in their hands. Usually they ask if I have anything I can show them and that gets the conversation away from me and my shop and now we are just talking furniture.
