Take a deep breath, wriggle you shoulders and relax. Take it slowly and as soon as you feel yourself tensing up, stop and take a short break. Remember that you're not in competition with anyone and that learning FMQ takes time and plenty of practice. If you take your time now, I'm sure that you will get to love it. It gives you so much more freedom with your quilts. Best of luck, I'm sure you're going to master it without too much trouble.
