What an interesting discussion. I took a 3 hr for 6 weeks basic class when I first started making blocks that were not just square blocks sewed together. I thought that taught me all I needed to know. I have since learned that even though we are taught how to do things we still have to be accurate in our cutting, sewing and press with care. My mother was a stickler for doing thing the way they should be done not just do them to get them done. So, I agree with everything that Jacque said and I think accuracy it the single most important thing to learn.
