What can I get for Christmas?

My mum usually gives me and my sister a budget of £250 each. I don't really want anything super expensive, if anything I just would like a few homemade gifts but I don't think my mum is deep enough for something like that. I already have a laptop, an iPhone, a wii, tv, camera etc. But I don't want anything else like that. I'm a 14 year old girl, and I'm not particularly interested in clothes, makeup. I love Demi Lovato, and all I've really asked for is a Demi Lovato 2013 calendar and a phone case. I like to play netball and I was going to ask for a netball hoop that goes on the outdoor wall, but our garden is really small so I would have much space to move around. Sorry for the long paragraph, just trying to give lots of detail haha. Any ideas?

Added (1). Also, I'd like to ask for some money out of my gift budget to do something small for my dad as it's anniversary on Christmas day. We usually let off lanterns with messages on them but we do that for almost every other occasion for him (birthdays, fathers day etc) and I want to do something original. It's his second anniversary this year.

Why don't you ask for £50 in cash. And if your mom ask why, explain that you want to use it for your dad. That leaves you £200. Not sure how much the calendar and phone case are, but those are good gifts to ask for. Just try to think of some other stuff that you really want. There's still a good two months before most people even begin thinking about Christmas shopping. If you still can't think of anything, I'd ask for the netball hoop, because it sounds like you really like it. Eventually you'll find a good place to put it.

Well what i'm getting is a membership in the local gym so i can go swimming whenever i want if that helps: P You could ask for tickets to demi lovatos next concert or her albums if you don't already have them. An itunes voucher? A nice piece of jewelery?
I don't really have any good ideas for your dad, sorry!
Hope i helped and that you find something nice x
