One year I gave my mom sweatshirts with IOU a design of your choice on them because I didn't have time to embroider them. She loved it! We had a grand time choosing exactly what she wanted!
I think you've gotten some good advice from this board. Just remember what the REAL gift of Christmas is. Sometimes I have to remind myself we're celebrating the Birth!
I'm the choir director at church and very busy at Christmastime. Then, last December I had hand surgery so I started a new 'tradition'. My choir members get gifts on Epiphany which symbolizes when the wisemen visited the baby Jesus.
Take care of yourself, so you'll have many more holidays with those grandchildren. YOU are their best gift ... they'll remember that some day with great fondness.
