Our Top 5 Under the Sea Party Supplies

Looking to transform your venue into an under-the-sea-themed party? Shindigz has numerous supplies that will complete the look, but get started with five of the most essential items. Use water patterned gossamer or iridescent fabrics to cover walls or objects. Place a photo background in a high-traffic area for realistic photos, too. Sea creature balloons are perfect for bringing a 3-D element to your party, and they move in the air just like they would under water! If guests will be staying for snacks or cake, make sure your tableware fits the theme, too, with sea-creature plates and centerpieces. But most importantly, don’t forget to send them home with a treasure chest of goodies!
