That is a beautiful quilt that your grandmother made for you, a wonderful heirloom. She must smile brightly when she sees you gently inspecting and folding it up again.
How unfortunate you didn't get to learn quilting from her before she died. Something like that happens to all of us, we think there is lots of time to learn something from a grandparent, then the time is gone.
