I'm 62 and I plan to make quilts until I can no longer hold a needle in my fingers, or push the foot pedal on my machine. I can't even conceive of quitting, though I know that eventually I will not have an option.
I have asked that I be allowed to live as long as it takes to finish all the quilts I want to make. I figure if I'm lucky and my request is granted, I'll be 187 before I die!
I also have RA, which increases the difficulty factor, but I won't let that stop me from doing what I love!
