Notepads

Hi! Anyone know how to make your own notepads? I’ve usually used online printing stores but if there’s a way to do them on my own it might be cheaper especially to order in bulk!
It might be harder because I would need glue and cardboard for the back no?
Is there a way to print the paper the exact size you need for the notepads and not have to cut each one? Let’s say I want 4 by 5.5 size paper for the notepads?

If anyone has done this before or has any idea how, feel free to let me know!
