Marcy,
I will be 70 in Nov. From time to time I have the very same feelings . However, I decided that all of those
great & great-great grandbabies that are in the future, need a quilt from G.G. Frequently made with scraps from their parents' baby quilts or graduation quilts.
Also, I have 8 more grandkids that will need High School Graduation quilts.
All of the above keep me reminded of "WHY" I continue quilt. And it keep me at the machine.
