I want to give her some origami. What should I fold? Besides paper cranes, hearts and stars, what else?

Stars can be folded with paper, or you can go to stores and supermarkets to buy plastic pipes with various colors to fold stars, which is not expensive. You can ask him to teach you or look it up online when you can't fold it. If you fold them with paper, you can write a sentence on each piece of paper to make her open, and he will be very happy.
