Mermaid Party DIY Ideas
DIY Mermaid Birthday Party on a Budget (Using Dollar Tree + Amazon Finds!)
Throwing a magical mermaid birthday party doesn’t have to drain your wallet or your energy!
Whether you’re celebrating a little girl’s milestone or creating a splashy summer bash, you can pull off a dreamy under-the-sea celebration with a mix of Dollar Tree treasures and a few Amazon touches.
Here’s how we created a Pinterest-worthy mermaid party full of color, sparkle, and sweet ocean vibes!
The Theme: Mermaid Magic with a Pop of Color
Our color palette included pastel purple, aqua, coral, and pops of hot pink, with hints of gold for a whimsical finish.
We used mermaid tails, seashells, and starfish to tie the theme together across every element.
Dollar Tree Finds That Made a Splash!
My bestie Mona from Far From The Farm hung out with me and helped set up – and she grabbed this quick video of the tablescape we created:
1. Mermaid Plates & Napkins
We scored the cutest mermaid tail plates and napkins in coordinating colors for just $1.25 each. They were the perfect way to keep things themed without needing expensive custom designs.
2. Plastic Cutlery in Bright Colors
To match our mermaid palette, we grabbed bright pink and teal cutlery packs and sorted them into mason jars for an easy, decorative display.
3. Tablecloths & Burlap Runner
The lavender tablecloths gave us a soft base color, and we layered them with a Dollar Tree burlap runner for a beachy, textured feel.
4. Shells & Confetti Accents
Loose seashells and gold circle confetti made for the perfect low-cost table scatter that tied everything together.
5. Birthday Sign & Flowers
We purchased a Birthday sign that’s white & gold and added faux flowers in mermaid colors for a DIY centerpiece that looked way more expensive than it was!
