I don't think that we intentionally try to confuse new quilters, but I can see how it can happen! We each have our own machines, rulers, cutting mats, thread, needles, etc. They can all differ. Then add in the "eyes of the beholder" and let the confusion begin! As you gain more experience, you will trust your own instincts more. In the meantime, ask questions and try suggestions. If that doesn't work, ask again!
