As a quilting newby, I am starting to read and work through the Hargraves' book, Quilter's Academy, Vol. 1. In the first 2-3 lessons, they talk the need to straighten your fabric, the wisdom of tearing vs. cutting fabric, and so forth. The couple of other books I've read don't even mention this level of perfection.
Do those of you who are experienced quilters find that taking these steps is necessary to make nice looking quilts?
