Under the Sea Theme Party Decorations

Under The Sea Decoration Ideas For Parties Large And Small

Whether you’re planning a grand gala, small birthday or large quinceanera, an aquatic theme is as easy to create as it is versatile to use. You can go for the breath-taking glamour of Neptune’s kingdom, the whimsical humor of frolicking sea creatures or the mystery of buried treasure and a sunken ship. A mermaid birthday party for a girl or a pirate theme for a boy. Change it up the next year and plan a SpongeBob bash. Many decorations bought for one theme easily translate to the underwater tableau required for another. With the variety of invitations, tableware, props, hangings and more available at Shindigz, you can find everything you need to make your under-the-sea party awash in success, no matter how big or small your gathering.

Under the Sea Party Decorations A Hit With All Ages

For children, a great aquatic adventure can be as simple as ensnaring assorted fish in a net and hanging it overhead. Position a kid-size cardboard octopus by the door both to welcome guests and create a photo op. Make balloon bouquets or hang a single Mylar dolphin, whale or sea horse to complete the room. After the party’s over, hand out the balloons as favors. For adults, gossamer is a fantastic fabric for creating a watery look. Cover the ceiling, hang it from the walls or drape it across tables. Strands of light underneath will enhance its colors and create the impression of movement. A variety of standees – seaweed, treasure chests, seahorse chariots – can complete the décor. Shindigz also carries themed under-the-sea standee packages that make decorating even easier.
