Practice, practice, practice. I tried to teach myself but got frustrated and would have quit. Luckily, one of my LQS had a class in FMQ and it was the best class I have taken. Of course the teacher made all of the difference. She is very talented and more than willing to share her knowledge. She would be honest in how we were doing yet it did not feel like criticism, rather information. I feel very lucky in meeting her and all the other quilters in my quilt gild like her.
Anyway, her encouragement helped me to continue and each quilt is better than the last.
Relax, have fun and keep us posted on how you are doing.
