This is the type of thing that discredits a teacher or shop. IMO, this violates the trust of students. I've been experiencing this too, classes that are as much a commercial as a class. But to give such blatantly wrong advice just to generate sales? Blech! Bob Purcell, president of Superior Threads, teaches a thread seminar. He doesn't criticise other brands, and he says we should put quality thread collections in our wills.
