My grandmother died when my mother was 8. She had done sunbonnet sue blocks for a quilt for mom, but passed before the quilt was completed. My mother kept the blocks and when I was about 10 completed them and quilted it for me. I still have the quilt 35 years later and mom was about 50 when she did the quilt for me. (very late in life child). So I am guessing the original blocks are maybe 75 years old? One of them just disingrated.
