Maybe that's what works for her, but you need to do what works for you. My favorite quilting machines are a 1907 Singer 27 treadle and a 1951 Singer 15-91. I love them both and they certainly aren't fancy. I have a Janome that does everything but sing and dance. I use it for embroidery-period. Find your own methods and materials. I always prewash because I'm afraid of shrinking or fading. I wouldn't worry about what she say, nor would I go back to one of her classes!
