Decorating with stickers?

In previous years, I’ve had the Cousin and A6 but for 2026 I decided to try out the Weeks. I got it in Strawberry Milk, and I got the clear cover to go over it. I have seen a lot of people decorate the outside of their Weeks with stickers, and I think it looks super cute. This is where my question comes in: do you put the stickers directly on the Weeks itself, or do you stick them to the clear cover? I’m assuming people do it various ways, but I’m trying to figure out the way that offers the most longevity.
