my impulse would be to make a couple of donation quilts, and on the label note that they were made with love in honor of your mom and/or sis, and take a photo of the label for mom/sis. then, give the quilts with that love to an organization that will put them in hands that will love them. win/win! you get to create, you get to "give" them to mom/sis, and someone who could use the "hug" will get that quilt to warm them.
