When should my sister start thinking about her birthday party?

I'm sure your sister has a lot of school stuff to do, and it would be better if her party could be planned sooner or later, not right now. So I have a suggestion: a girly sleepover. Here's a guide.

Invitations:

-Print your party details in large block letters on clean, white pillowcases. Fold them and send them in manila envelopes.

-Mail your invitations along with a small teddy bear or stuffed animal for your guests to bring to the party.

-Punch a hole in the corner of a card-style invitation and attach it to a new toothbrush and a small tube of toothpaste. Your guests can bring these items with them to the party! Mail your invites in padded envelopes.

-Here's an invite idea.

Are you ready for some giggles and gossip?

Maybe some pizza, and some chips and dip?

Then come to Ella's party and bring your pj's,

'Cause it's going to be fun in so many ways!

Decorations:

-Streamers and tulle around the room

-Glow-in-the-dark stars on the ceiling

-Pillows, sleeping bags, and blankets around the room

-Popular music that your guests can dance to (like Super Bass and Pop by NSYNC)

-White twinkle lights around the perimeter of the ceiling

Food at night:

-Funny Face Bagels. Spread cream cheese on bagels then decorate with jelly in a squeeze tube.

-Relaxing Refreshments. Soda, strawberry milk, and juice with silly straws would work.

-Popcorn Passing. Give everyone a bag of popcorn and pass around the flavors such as powdered cheese or barbecue powder.

Food in the morning (breakfast):

-Smiley Face Pancakes. Decorate pancakes with toppings such as whipped cream, chocolate chips, chocolate syrup, finely chopped nuts, blueberries, and more to make them look like Smiley Faces.

-Waffles. Let your guests choose their own waffle toppings such as cherries, whipped cream, strawberries, chocolate chips, and nuts.

-Fruit Pops. Slide sections of fruit, such as pineapple, banana, strawberries, and grapes onto a wooden skewer and serve.

Games and activities:

-Make your own scrapbooks. Provide the paper, coloring materials, beads, buttons, stickers, and more.

-Play the traditional party game Telephone.

-Name That Tune. Give each guest a chance to pick 5 songs from YouTube and let the others guess. After three rounds, the winner gets a unique prize.

-Play the traditional party game Flashlight Tag.

-Bake cupcakes with your guests. After that, have a cupcake decorating contest! Provide the cream, sprinkles, chocolates, and more.

-Create a fun scavenger hunt for your guests.

-Like what you mentioned, setting up spa-themed activities or beauty stations would be good. How about a mani-pedi station--or a hair perm station? :)

-Watch fun chick flicks such as:

The Notebook

Monte Carlo

The Sisterhood of the Traveling Pants

The Princess Diaries

Ella Enchanted

Aquamarine

Girls Just Want To Have Fun

Never Been Kissed

The Princess Bride

A Cinderella Story

-How about other cool movies?

Alvin and the Chipmunks

Nanny McPhee

Harry Potter

High School Musical

Hugo

Lemonade Mouth

The Secret Garden

Diary of A Wimpy Kid

Titanic

The Ring

Paranormal Activity

Favors:

-Pillowcases

-Lotion, lip gloss, and nail polish

-Candy

-Stickers

-Costume jewelry

All you need to do here is purchase some stuff, print the invitations and get crafty for making decorations. Easy, huh? This party theme is good because your sister can plan later, but remember; the earlier, the better. I hope it helped. XDD

Now's a good time to start planning the party. She has more than a month to prepare and that's good enough to plan and organize a great party. She should start first with picking a theme for the party. This will be her guide in selecting the design of her birthday invite, the decorations, food, party favors, games, music, and her dress, too. This might help give you more ideas on themes, costumes, and party supplies you need: http://www.partiesonline.com.au/

if she wanna give party on large scale then she must start thinking atleast 20 days before the birthday and if she wanna give a good small party then 4-5 days will be enough.

about 1 month before.
