Like fanc36, I am also enrolled in more than a dozen classes both quilting and sewing. There are a few that I didn't enjoy, have received refunds on 3, but the majority I have really enjoyed.
I like *most* of the teachers but there are some that drive me crazy, I think that's a personal preference.
*TIP* If you don't like a class, give it a 2 star review and you will get a refund.
