To bring out the pink from the balloon garland and mermaid banner, we used the light pink cutlery set at each table setting. We also added pink and white striped straws to the cups.

Scatter some colorful and shimmering mermaid confetti down the center of the table to add some magic to your mermaid party decorations.

When all the little mermaids at your party are ready to go home, send them home with these cute seashell favor bags filled with sweet treats and mermaid-themed party favors.

We used our pink and white striped scalloped napkins in the favor bags instead of using tissue paper. This is a perfect example of how to use items for uses other than what they were meant for. Plus, the pink and white napkins go perfectly with the pink cutlery and the pink and white striped straws.
