Ask someone in the Houston Hotties. (HSGB on Meetup.com).
I think they still meet the 2nd Sunday of the month, but someone on the Meetup group should be able to help you locate classes.
At one time Leah was teaching out of her home studio in The Woodlands. This is her web page: http://www.leahbeads.com/about.htm
Diane Woodall (a member on LE) was teaching at her home studio. You could send her a pm on LE to find out if she is still teaching or check out her web page: http://dianewoodall.com/
If you do not find what you are looking for, shoot me a pm.
