Party ideas please!! I need help?!

You mentioned make-up, you could also do hair and nails and let the girls work on each other. Take 'after' pics of each girl with yourself, the birthday girl, that you can send to each one afterward, and also for yourself to include in a scrapbook or photo album. :) If you have pictures of you and your friends when you were all younger, you could pull those out and see how much each of you have grown. Girls love looking at and taking pictures! :)

Food ~ Pizza is a great choice. It's easy and quick...you could even buy cheese pizzas and take sections and let each girl add a topping of their choice. Kind of like a pizza 'sampler.' So that they're each assured to get the kind they like. Or you could even make a pizza as the dessert for your party and do the same with different toppings....like a chocolate pizza.

Another idea is to make something like tie-dye t-shirts (and it won't be long before the girls can wear them!). We did this once for my daughter's birthday and it was a bit hit - the girls brought their own plain pre-washed white t-shirts and we supplied the dye (we just bought a kit from Wal-mart). They gathered at the dining table and went to work on their work of art. The colors and t-shirts all turned out beautifully and the girls were SO excited to have matching shirts and also something that they created themselves.

Have fun! Congratulations on turning 13! A very special age for young ladies! :)
Happy Birthday, Madison! :)

you should just have pizza, cause its pretty cheap, and you dont have to spend time making it.
