Sticker Pack will be updated constantly. Big surprise extension for Easter! 🙂
Please feel free to send your ideas. I will add your name to the list of contributors.
After downloading, start your Messages App, tap the A symbol next to where you would normally type to send a text, and open the sticker pack. Tap or drag the sticker to the text field. You can even construct your own sticker by dragging more in the messaging field.
