Please don't give up. When I started FMQ I was horrible. I hated it. I was so stressed by the time I finished a piece my shoulders and back were killing me. But I kept trying. I just finished a Happy Daisy wall hanging for my office. I stippled around the Daisys and yes I was exhausted afterwards. But my husband, who never compliments me, said I did a fantastic job. He just loved the quilting. When I looked at it he was right it was pretty good.
Moral of the story, keep trying! Practice and keep trying. I know I am going to do more.
