A good teacher should tell you all of the different ways to do something, but explain why she prefers her method. If you're happy with the results you get, keep doing it your way. If you don't like your own quilting results, try other methods until you find one you like. To me, quilting is such an individual thing and everyone does what they like the most. I use a walking foot to quilt on my DSM because I didn't like the puckers I used to get on the back side. I've never done my binding using the bias. I don't like to pre-wash any of my fabric, because I like the stiffness of the sizing when I piece my blocks together. Just because this works for me, doesn't mean everyone else wants to do the same thing.
