I wish I could help, I only have the crochet experience. I plan on making a Marceline plush for a friend, and that's pretty much it. I'm also not great in the grandma experience department, either.

I don't know if you have cooking skills either, but there's always a jar of cookie ingredients or something similar. Or decorating a container/bin/tub? Does she like plants? You could also do a decorated pot for a potted plant.

I've seen really cute notebook decorating ideas online as well.
