Last spring I finished a quilt for my mom that included pieces that her mother had cut out. It had a very cool, detailed story and I documented it all so that many years after I'm dead and gone, my great nieces and nephews know the story - or if the quilt ends up in someone else's possession, they know it.
I will always label the quilt w/ dates and places and try to personalize it for the person I am quilting it for.
