What happens when the party supplies queen, Jen of The Cupcake Social, throws a rainbow-themed birthday party for her daughter Regan? An absolutely fabulous explosion of color, that’s what! Jen made Regan’s party so so bright and happy, just try to look these photos without smiling. : )

The black backdrop – simply foamcore, purchased at Staples – sets off all the colors and the bright white cake.

Jen said that the water bottle labels were a huge hit with the children. : )

Jen put stickers onto scallop-punched paper, then glued the circles onto striped straws. They’re just adorable stuck into mini buckets filled with gumballs. And, Jen made her own tissue paper poms. Pretty darn crafty!

Paper straws in every color – all from The Cupcake Social.

Jen says, “I wanted the icing to look like fluffy blue clouds by mixing the white frosting and adding some that was tinted with blue food coloring into the same piping bag. I also used edible gold stars, so cute!”

I also love the new idea for a favor tag – stuck on a straw! Super clever.

The fabric banner than Jen made for Regan’s party is now available by custom order in her Etsy shop!

The cake was inspired by The Whisk Kid, but Jen added a PINK layer. (Awesome.) : )

The children had fun doing sand art, rainbow scratch art, and coloring pages.

Goodie bags include rainbow crayons from Oriental Trading, and are topped with a treat bag label.

Beautiful cookies by TS Cookies are a perfect take-home treat at the end of the party.

Thank you so much, Jen!! Happy birthday Regan!
