You have to do that through the "Game Center" app. 1st hit that, then go to "Requests" and on the top should be "Friend Requests" with a + button on the right hand side. Just hit that, and type your sister's name in and add. She has to "accept" your request though. Then, if you go back into the game, you'll see her name (username for the Game Center). Then you can hit the "Send Gift" button by her name. Hope this helps! :D

lemonl!me is my username for example. :) Good luck & happy exchanging!
