Gift ideas for a 10 year old girl?

I'm pretty much in trouble! I have just 1 and a half days to quickly slide a gift under the tree for my 10 year old sister! I realized that I felt bad about only getting her 2 headbands, a ring, and a make up bag. Yes those things were only a dollar each! I've searched the internet for ideas and all I can find is a tea set or a bug catcher. Seriously? I was into that kind of stuff when I was maybe 6 or 7. At 8, I was totally grown out of it! She already has the cell phone and the ipod touch, so I'm all out of ideas! She's not into stuff other girls her age are, but everything else is really innapropriete! I tried to find her something when we went shopping, but she clung to my hip the whole time so I couldn't really be 'sneaky.' I asked her to write down what she wanted and here's her list: Earings, mini fridge, vampires suck, eclipse, shoes, colorful camo dress, and a 'diva' necklace. I can pretty much say no to everything on that list. Her favorite color is apparently black. She's not that into a specific band or artist, she more just listens to everything that they play on the rap channel. So that means Eminem, Flo Rida, Mike Posner, etc. None of which I can stand to buy her a CD so she can blast. She's really into fashion and makeup (she's not allowed to wear it, but she steals mine when I'm not looking). She's not really that into animals so that rules out a stuffed animal. My budget is flexible, but I don't plan on spending more than $20 dollars or so. She's into sewing and cooking (mainly pie baking). Anyone have any ideas for gifts?
