I took a class once at NQA by a nationally known lady I wont mention her name. But I was so very disappointed. Every other word was the name of the sewing machine company that hired her to be their star. I was not happy as it was so hard to get the information on the technique . All that was being covered it how great this machine was. I didn't pay for a commercial. On the response sheet on rating the class I did bring this up. She never came back that I know of. But the other ladies where so mad some walked out. Not me, I paid for this class.
