Toy Story 3 Jessie Themed Third Birthday Party Setup
Your daughter is going to lose it over this Jessie-themed setup. I’m obsessed with how they used cow print balloons mixed with those peachy pink and mustard tones, plus the little traffic cone drink bottles are such a genius touch. The Toy Story 3 cutout with the “You’ve Got a Friend in Me” shelf display brings the whole western vibe together without feeling too cowboy-heavy.

Kids go absolutely wild for a balloon setup like this. You’ve got giant donut balloons, an ice cream cone, and those fun directional signs that say things like “Donut Worry Be Happy” and “Eat More Hole Foods.” It’s colorful, totally Instagram-worthy, and honestly makes the whole party feel like you rented out an actual donut shop.

Your little Barbie fan is going to be mesmerized on this one. Pink sparkly table runner, those adorable clear acrylic trays filled with beads and crafts at each seat, pink bowls and place settings, plus that massive balloon garland in every shade of pink you can imagine.
Princess Belle Beauty and the Beast Birthday
I love how this setup goes all in on the Belle theme without looking like a party store exploded. Those scalloped pink plates with the princess illustrations are such a nice touch, and the floral centerpiece in peachy pinks and roses is actually really pretty (not cheap looking at all). You can spot the Belle standee in the background and those custom water bottle labels that make everything feel super coordinated.

You could totally scale this down or DIY parts of it depending on your budget.

If your daughter is unicorn-obsessed, she is going to absolutely flip over those life-size unicorn props.

If your girl loves dinosaurs and sparkle equally, this outfit gets it. You’ve got the punny ‘ROAR I’m a THREE REX’ shirt with that adorable purple dino wearing a party hat, paired with a pink, purple, and turquoise tutu that has a huge gold sequin bow. Both headband options work too, the floral one or the simple gold bow, whichever matches her personality better.
Madeline-Themed Oui Oui Emery is Three!

Look at all those rolling pins and colorful clay blocks set up at each spot, plus the bins full of beads, pom poms, and craft supplies down the center.
