I want to make homemade gifts for Christmas. Got any ideas?

I just learned how to crochet a few months ago. I also know how to sew. I'm still at the beginner/easy level for both. I want to make something for my grandparents but I can't think of anything. Here's some info on my grandparents: My one grandma is very crafty. She loves to sew and crochet. My other grandma loves to bowl, watch Nascar, and play on the computer. My one grandpa loves to read books and play golf. My other grandpa loves watching sports and movies, playing golf, and playing on the computer. Does anyone have any ideas?
