OK, everyone else says to keep trying - I also say - DON'T be so hard on yourself. Don't look for the mistakes, just practice and go with the flow. Sometimes, it's harder than others, but keep trying. Do some practicing on paper just by drawing what you want to quilt. It sounds goofy, but it does help. Have you ever tried to fmq your name? You will be surprised at how nice that looks. That's because you have written your name like a gazillion times.
Don't give up!
