You are not old! I'll be 80 in March. Just, as others have said, don't expect to "get it right" the first time. I recommend making practice squares and working a little each day. I have found that about 8 hours of practice time, spread out over several weeks, making sure that you watch where you are going, not looking at the needle. Good luck and let us see your progress. (I am a left-handed quilter with a damaged hand from heart surgery and had to learn to FMQ.)
