Way too pricey for me to consider. I've only taken one "famous quilter" class- Bonnie Hunter at the Vermont Quilt Festival about 4 years ago. It was about $40 for a 1/2 day class, plus registration fees, etc so a total of about $70 plus travel costs of about $30. We brought our own fabrics precut into 2 1/2"strips. Well worth it to me for some fun and seeing the quilt show. I rarely take classes or go on retreats since I am in a Guild with occasional "Quilt til You Wilt" days during the year, and I have a nearby sister to sew with.
