I wish I had become interested in quilting years ago, but it wasn't until I was 78 that something happened to peek my interest. I'm now 80 years old and have produced quite a few quilts, wall hangings etc. They are certainly not the most professional, but I like them and most people I give quilts to seem to be very pleased with them. I honestly don't even think about when I am no longer here and just enjoy everyday that I wake in the morning. I honestly believe having an interest, or a passion in life makes one younger and plan to quilt up a storm (at least in winter) until I can no longer move my fingers.
Enjoy your hobby for as long as the good Lord allows!
