- Serve finger food like mini sandwiches and fruit cups.
- Start the movie right after sunset.
📸 Plan the evening
Set up the picnic table in the afternoon.
Serve dinner at golden hour.
Cut the cake before it gets dark.

A fall birthday? Turn plain pumpkins into sparkly works of art.
This New York party company sets out small pumpkins with pearls, rhinestones, and gems so each girl can glam up her own. It is easy, a little messy in a good way, and every guest leaves with a cute decoration.
Use small craft pumpkins and strong craft glue dots instead of hot glue for younger hands.

Two crafts tweens love most, at one party.
This LA setup has a pink lip gloss station where girls mix shimmer and scents, plus a squishy bar where they build their own squishy toys. The pink table, mirror, and lights make it feel like a real beauty studio.
You can buy lip gloss making kits online. Pick kits made for kids with safe, simple ingredients.
Good to know
Set the gloss station on a table with a plastic cover. Shimmer and oils are hard to clean from fabric.

Tie dye never goes out of style, and every girl gets a shirt to keep.
In this summer party, the birthday girl and her friends roll and band white shirts, then add bright dye in pink, blue, and rainbow colors. The party also had a slime station for extra fun.
Do this outside and give each guest gloves and an old apron. Shirts need a few hours to set, so send them home in zip bags.

A dance studio gives you space, mirrors, and music, all in one place.
For this 11th birthday in Manhattan, the girls made squishies and custom lip gloss, then danced at a pretty studio. A party like this works great for a 12th birthday too, since girls this age love to dance with friends.
Many local dance schools rent out their studio on weekend afternoons. Ask if a teacher can lead a short dance class.
Quick tip
Ask the studio teacher to teach one short trending dance. The girls can film it together as a birthday keepsake.
