I have been doing FMQ for a little more than a year now and love it. I have to admit that I was terrified of it at first. Now another friend and I started a small group of ladies that want to take it a little further by sharing patterns and knowledge. We meet once a month and each month we change off and a different one brings a pattern to practice on. One of the things I was taught early on was to sit and doodle with pencil and paper every night while watching TV and then try it with my machine. It has helped me get my rythem down when I try it on the machine.
Like others have said, if you don't like it then don't do it and don't beat yourself up. It is not for everyone. Maybe at another time in your quilting career you will be ready to try it again.
