When I started quilting QNN was free then Fons and Porter bought it and now it costs. But for a beginner it is worth the money to see all the videos and there are a lot.
Eleanor Burns is by far the best teacher and her videos are free on her website under the television/video button.

Her books are very easy to follow and if you watch the videos that go with the book you cant go wrong.
