All of my grandparents are deceased now but I remember when I was younger spending time sewing or "helping" my grandmothers sew. I would give anything to be able to do that today. Give them a card with a coupon for one on one time with you sewing something they then can take home. It will be a present they will remember their whole life. I still have a teddy bear I helped make. I really spent time with my grandma while she made it but I love that bear with all my heart 35 years later.
