Okay kiddo, have you ever seen a sticker album before? It's like a special book that has pages with spaces to put stickers in. You can collect stickers and try to fill up all the spaces in the book.
So let's say you love unicorns, and you have a sticker album with unicorn pictures on every page. You want to fill up all the spaces with unicorn stickers. You can buy packets of stickers from the store or trade with your friends to get ones you don't have yet.
Then, when you get a new unicorn sticker, you can put it in one of the spaces in the book. You have to be careful and stick it in straight so it looks nice and neat. And you can't put two stickers in the same space, because then you won't have any more spaces left to fill.
Collecting stickers for your album can be really fun and exciting, and it's a great way to keep track of all your favorite things. Plus, when you finally fill up all the spaces, you'll have a whole book full of unicorns (or whatever else you love)!
