When I am teaching a class I tend to teach the best way that works for me. But I always emphasize that "my" way does not work for everyone and if you find a different technique or tool that works better for you, then go for it. I also let my student decide if they want to rip out or not. I might say, "I would rip that one and do it again, but if you are happy with it then it is OK." If everything has to be absolutely perfect, I agree, sometimes it takes the fun out of it. Let's strive for stress-free and fun quilting!!!
