I was too afraid to 'ruin' my tops with bad quilting, when a friend asked me to assist her with charity quilts. She was really 'forcing' me to practice,practice,practice. I am now fairly good at it (and still learning). You have to either find charity quilts to practice on, or do small bags and pot holders etc until you become acceptable. It doesn't take long once you get the hang of it, and all your fears go away. My moment came when people started to ask me how much I would charge if I would quilt their creations for them. However, the best (for me) was when a lady, whom I consider to be a very good piecer, asked me to quilt her quilt for her...Have courage and I think you will surprise yourself as to how good you can become.
