Brenda Papadakis is in Texas. I had her last year at Empty Spools.
Jan Krentz, but she is West Coast.
I was told that Judy Neimeyer is very good (Montana). Paula Nadelstein is very good (New York). She came to my LQS once for a day workshop.
Gwen Marston (Michigan) is very good. She has taught at Empty Spools as well.
It also depends on what interests your guild has.
