You can use a lot more stickers in your Instagram Histories than you might think. This is a very simple trick but it will make your Stories a lot cooler and more original.
To discover new stickers:

- Create an Instagram Story as you normally would, but don't post it yet
- Add a sticker by clicking the Sticker Icon in the upper right corner
- Tap on the sticker, this might change into another sticker. Note that not all stickers change.
