I gave up a family vacation because I had already signed up for a mystery quilt seminar by Billie Lauder. I had seen her on several tv quilting shows and really liked her. The instructions prior to the class were pretty clear and many of the pieces were to be cut prior to the class. There were about 25-35 members of my quilt guild in attendence. We were pretty much left on our own as Ms Lauder sat in the back of the room surrrounded by all of her products and her primary interest was in selling them. When I saw her finished quilt I was so disappointed I never would have taken her class had I seen it beforehand. She said that she had just used what she had lying around and it showed. It was made of ugly federal blue and gray. I decided to make mine in just a child's size which turned out very cute in different colored and sized dots. I won't pay for a class again but might do a free one on the internet.
