Practice on something first. Cut a piece about 10 x 10. Next batting and backing. Use it first to make sure that you have your tension right. Then if you haven't dropped the feed dogs, dropped those puppy's. Pull up your bottom thread to the top and get r done! Practice until you can't figure out where you started and stopped at. By then you will have worked the kinks out in your armor and you won't be so tense in the shoulders and then take a leisurely stroll with your machine. If your still tense, practice on something more. Tenseness will cause all kinds of problems. Eye strain, headaches, back and neck aches. Remember: there are NO quilt police. Everyone has a learning curve. As you master one thing, you will learn something else. Your confidence will grow and each quilt will be more beautiful than the last one. Post your first one after your done. I think you'll be pleasantly surprised.
