What are the ways to create double eyelids for eyes without them, other than surgery?

Since I don't have double eyelids, my eyes look very sharp.

My eyes look small, too.

I'm so scared and nervous about double eyelid surgery (I'm afraid I won't like it after the surgery, haha, and you can't turn it back).

Do you have any recommendations for double eyelid tape or anything like that?

Please recommend a product that can easily create double eyelids!!! I want my eyes to be bigger!!!!!!!!
