Isn’t this painted backdrop Jacqui of Deets & Things made to complement these incredible cakes from Sweet Deetails just perfect? Jacqui has designed quite a few birthday bashes for this sweet fam all in their same backyard, which we’ve featured on Cakelet over the years. From the modern camp themed birthday to the “party like an animal” bash to this tropical 2nd birthday, they’re quite a testament to all the routes you can go for a party right at home. Thanks to Caitlin Alohilani for capturing all the under the sea fun!

Jacqui explains, Archive Rentalsâ new childrenâs line Archive Littles had an amazing selection for our little ocean party, making my job easy! I wanted the shark and mermaid table to be different but complement each other and hence, the hobnail paper cups, napkins, utensils and little details were the same on both but in different colors. As per usual, Not Just in Novels did a brilliant job of capturing the essence of seaweed and coral reef respectively on each table.

The Deets & Things crafted a structure above the kids table using ribbons and balloons. So fun!

And being a pool party, naturally they needed a big balloon install over at the cabana. Really digging this pink and blue palette!
