These party tips and ideas are solely for people who are NSYNC fans. They will find my thoughts and hints to be very useful, fast, and fun! 1. For invitations, decorate a red or orange piece of paper to look like a ticket to an NSYNC concert. Type your address in as the stadium's address. and include the birthday sleepover's date, time, and requirements (CD's, swimsuit, sleeping bag)on the invitations. Pass them out 2 weeks in advance preferrably.  2. To decorate for an NSYNC party doesn't take very long. Plaster tons of posters of the group along the walls and ceilings of the party room, but don't forsake a few traditional ballons and streamers. Cut-out magazine articles and newspaper clippings about NSYNC can be pinned up as well.  Move a boombox and a stack of NSYNC cd's into the party room also, and make sure parents will let you crank the music up before you do so! For a special and varied touch, scatter a few dolls and teddy's around the party floor for guests to sleep with. Tasteful decor will add to a wonderful party impact! 3. As for food for a party, it's basically chips, cookies, candy, and pizza. But to be more NSYNC-y, serve large pitchers of juice that are the favorite colors of the group members. Serve blue punch to symbolize Justin Timberlakes favorite color, etcetera. Also, have trays of food set out and labeled that (with research) you have determined to be an Nsyncer's favorite snack. That's about as peesonalized as you could get here.  4. No party is complete without things to do besides eat. Play games like basketball and hackey sack, which NSYNC members play frequently. You can custom order a pinata to fit your party theme. But, on top of it all, don't forget to play games like charades, truth or dare, and other ususal favorites. I've given you help, all you NSYNC fans, for a cool party themed after a marvelous fivesome, but it's your genius and your great friends that will bring this NSYNC birthday sleepover to life!
