Hi - We met you at the Milford CT art show on the Green a couple of weeks ago. We purchased a double wind helix, then talked on & on, until my partner got impatient. :-) Great website, by the way! My suggestion: include some pics of your works weathered to the green patina so we have a better idea if we want to preserve the copper or go to green. Thanks! howsmith@adelphia.net (Howard Smith)
