DD's teacher won't be back at the school next year

so I want to get her a present from me. She has been so good for DD and has given a LOT of her own time to her. I have the teachers presents from the kids organised, but this is something from me to her. I'm also writing a card naturally.
She's 24, 2nd year out of teaching, gorgeous, funny, bright and bubbly. VERY enthusiastic about work lol. She has an Iphone 5 and an Ipad...what about a case for either? I saw a gorgeous hot pink croc leather ipad case just recently.
Any other ideas?
