I have taken a Bonnie Hunter class. It was great fun. She limits the number of participants so you do get time with her. She also has a trunk show where you can get up close with her quilts. She gives tips on cutting and piecing that makes the process easier. If you have never worked with triangles, she has several methods to make you successful. And, finally, she is really fun!! I would go for it.
Oh, the class I took I originally hated the pattern, but loved it when it was done.
