Once you install the Birthday sticker packet you can access it in the sticker options in your your Doodle Wish app! Or you can go and install different sticker packets directly from within the Doodle Wish! app, just go to the sticker button and select "dowload" to choose any packet you like!
***Please note that this is a Birthday Cards content pack for Doodle Wish app. It is NOT an app in itself. It will let you install DoodleWish! first if you don''t have it already.
