I believe there are different teachers for different students. Unlike schools, the student needs to find the right teacher! If you don't like one teacher's style, move on to the next one.
Some quilters have some skills already mastered and really don't need the techniques shown in detail.
There are beginner quilters who need techniques broken down to simple, simple steps and sometimes there's different techniques to get to the same ending!
All I can say is WATCH AWAY!!!! The internet has made learning to quilt POSSIBLE!!! You can learn how to do almost anything on the internet. Think of how people learned to quilt before the net. Things were only learned 'hands on' from someone we knew. Then came t.v. shows that taught us how to quilt (Eleanor Burns, Fons and Porter, Alex Anderson, etc), quilting took off! Then the internet shows, blogs, tutorials, forums, etc...there's no stopping the love of quilting now!
If you want to learn ANYTHING about ANYTHING, you can probably find it on the net!
