Connie, I haven't taken any classes from Pearl, so I can't help you there, but Empty Spools at Asilomar is as close to heaven on earth as I can imagine! Gorgeous scenery, good food and accommodations, and quilting all day long
!! Plus, you get exposed to all the other teachers who are there because each evening, two to three of the teachers give presentations of their work. And there is a quilt store on premises during the week and shuttles to the local quilt store in the afternoons—both have a phenomenal selection. I've been twice and made good friends both times, which is a nice bonus.
