The background is always the most important aspect of a magnificent party table, and this Mermaid backdrop is no exception. The good news is that it is both inexpensive and simple to make, making it ideal for any underwater-themed party.
Cardboard sandcastle
On the party table, one or two cardboard sandcastles would be a great centerpiece. Making this would be a lot of fun, and the completed product would be stunning.

Under the Sea Theme Party Cakes
Tropical fish cupcakes are ideal for your celebration because you can be sure to catch some fish under the water.

Chocolate seashells on top of the cupcakes, on the other hand, are extremely lovely. It’s as easy as forming the chocolate mold and then pressing it into the cupcake after it’s set. The finished product is an excellent addition to any sea-themed gathering.
