You're right, right now she doesn't understand... but one day she will and she will she will treasure every one of them. So keep on quilting, and leave her a note attached to your finished quilts for when you've gone on to the big quilting bee in the sky, asking her to pass your quilts out at your funeral to friends and family who who would like a memento of your love. I believe when she begins thinking about having lost her best friend, she will treasure and want to keep every quilt you made as a source of comfort and later she will want to pass them on to her children, grandchildren etc. I know this because I treasure the couple of quilts I have inherited more than I ever realized I would when my GM was quilting them. Wrapping yourself in a quilt made by someone you loved who has passed away is as comforting as being hugged by them!
