Minh,
Do you check my
Events page periodically? There's several NC workshops on there and one is by Tom Edgerton in Greensboro, Oct 28-31. If they say it's filled up, you might be able to twist Tom's arm if you say you're a Forum member.
You missed two in Asheville given by Peggy Baumgaertner. There's one is Raleigh Nov 13-15 by Paul McCormack, also an SOG artist.
These are all fabulous artists and you couldn't go wrong.
