I do what works for me. I am self taught and I have won ribbons in our local quilt shows. It may not be the "right" way, but it is my way and it works for me! LOL
When I am teaching people how to quilt, I tell them they have to make sure they are cutting accuaratley, have to know the 1/4 inch seam rule, and the rest is preference. I can show them short cuts, but as long as you are happy with your work, that is what matters.
