What a sweet story!
I have a quilting friend who has a similar story. She has a daughter, when the daughter was maybe 8 or 9, her mom (my friend) started teaching her to sew and quilt. The daughter made a simple but pretty quilt, just squares of fabrics she liked, sewn together in a simple pattern. It got put aside for quilting "later" which then became "someday" and was eventually forgotten about. Fast forward many years, daughter is now grown, married, expecting first baby. At the baby shower my friend gave her daughter the forgotten first quilt; she had quilted it, bound it, and put a label on the back. When the daughter opened it, her mom said "Bet you didn't know you were making your own child's baby quilt" there wasn't a dry eye in the room.
