for me FMQ was an AHA moment but it tooks years of practice to get there. I can tell you it is not overnight and it does get better craftsy and patsy thompson played a huge role in me finally getting the basics down. I am not necessarily good at staying on lines but I am now decent at feathers and fill designs. My fave teachers are cindy needham, patsy thompson, and ann petersen. there is even a quilting with rulers class on craftsy
