My daughter turned 13 last year - she had such a fun party! My kid's favorite parties are the ones that they have had at their home. Usually she loves a sleep-over but last year, I allowed her a 4-hour party - on a small budget. Very fun!
The big event was a neighborhood scavenger hunt. I have a great list and set of directions. We actually used this the year before and the girls really wanted to do it again. Personal message me with your e-mail address if you would like a copy.
We also played several cute games, including a trivia game that my daughter made up, called "All about me" . I wasn't sure how it would go over but the girls loved it - it was 15 - 20 questions all about my daughter - she made it up and just asked ordinary to obscure questions "what's my favorite color?" to "what am I most afraid of? (tornados!). Some girls knew her better than others so she was careful in asking a variety of questions.
In the past, we've had "make your own small pizzas", which is fun. We've also set up taco / fajita-buffets and the kids love that. Serving decorated cupcakes on a cupcake tree (wilton's) is easy and elegant!
I wanted to come up with a couple fun games and, with a little help, created this game which was a take-off of musical chairs with a teen edge! That game was awesome - it was a good (but messy) game and the kids loved it! We got some great candid pictures. We also played "Guess-who-I-am" , (this is a great ice-breaker game!) birthday pictionary, memory game and the present game. If she's would have fun playing games - please personal message me and I will expound on any of the above.
Someone mentioned spa-day and that is very fun too. Having someone who is going to cosmetology school come to your home, can save a lot of money. Even a couple older, local teens can help out with hair, nails, hot-wax/hand bath (if you can find someone who owns one), small henna tattoos and finger foods. Or, what one of my friends did with her daughter - she arranged an evening with a local salon (who was not open late on a Friday night), to have the girls come in the evening on a Friday, and be pampered (on a budget!)... they did updo's and nails, had finger foods/cookies and punch, then went to a pizza place afterwards Treat bags were nail kids, nail polish, rhinestone hair picks and small barrettes. Also, a nice "treat bag" or gift remembrance for all the attendees is a CD that your daughter can burn with a medley of her favorite and memorable songs.
Have fun - whatever you choose to do!
