Since you are able to sell you pieces in New York, you may want
to consider some of the weekend getaway spots that New Yorkers go
to on a regular basis. There are galleries in major ski area such
as Stow, VT (I had sold a piece in one called Shimmering Glass in
Waitsfield) and there is a jewelry store at Stratton Mountain in
southern VT who caters to the New York crowd. I think the name
is something like Von Bergen. He carries exclusively designer
jewelry, very high end. There is also the Saratoga area for the
summer crowd, but I'm not familiar with what's there. Lenox, MA
has lots of galleries and $$$ (Tanglewood area). You could scope
these places out without spending a fortune on travel.
Hope this helps. Good luck!
