I've sold art and at one time Sarah Coventry jewelry - my family and friends never bought anything from me - although I sold a lot to strangers. My theory is, my family and friends expect stuff from me for free. Acquaintences however, are a different story.
You have to socialized and make true friends. If you do it with a sole purpose of selling a product then it will not work. Be true friend and make true ones.
It will realy work, of course in a long run. Even if you make friends online/ through social bookmarking sites, make true friends. Be honest with them. It will put you on the top.
I have been doing this since many years and I have a lot of friends who are always ready to help me in distress because I have helped many of them when in need without asking for or even thinking of a return.
