Who's your favorite Quilting Workshop teacher?

I received an email last week asking for recommendations for an African American quilting workshop teacher. I've only taken two quilting workshops in life. One was taught by Maryland quilter Barbara Brown, who gave instructions on Baltimore Album techniques, and the other from Penny Sisto. Can you help me to put together a list of 10 African American quilters who also teach quilt-making or quilt technique workshops? Who would you have on the list?

Update: Thank you for all the comments. Here's the list of workshop teachers to date.

1. Rachel K. Clark
2. Juanita Yeager
3. Teresa, Cowie Quilts
   
4. Barbara Pietila
   
5. Valerie White in Louisville, KY
   
6. Adriene Cruz in Portland Oregon
7. Carole Samples workshops on Crazy Quilt stitches
8. Anna Fogg in Maryland specializes in folk art needleturn applique
9. Do feel free to leave more suggestions!

Juanita Yeager - 2007 Symposium

Juanita Yeager is hosting Quilt-Fiber-Art Design Symposium in four sessions during July 2007 in Durham, North Carolina. The sessions are open to all quiltmaking levels from beginner to expert. According to Yeager's website, the "symposium is a combination of lectures, demonstrations and hands on practice sessions. In this format a variety of techniques useful for making contemporary traditional quilts and art-quilts will be taught with ample time allowed for hands on experimentation by all participants." Visit Juanita's website or email her at jyquilts@mchsi.com for more details. The photo here is of Juanita's own quilts titled "Come Sunday Morning."
