Summer birthday bashes have gone the way of flamingo fare, pineapple parties, and cacti celebrations. With fall now in the air, we’ve gathered the party themes that are heating up! Whether it’s LEGO NINJAGO character masks or a jump-party hookup, flip through for the trends of the season that are sure to carry us through the school year. And, yes, there’s unicorn cake.

Super Smash

Calling all superheroes and heroines! Challenge everyone to don a cape or mask. (Parents has some awesome DIY templates.) Make use of another hot trend by serving up some slime for everyone to take home. Your little wonder women and super men will love it. Soirée Event Design has a fun Ninja Turtle Party slime recipe at the ready.
