How to Host a Maritime-Themed Due Date Pool
1. Anchor Your Aesthetic
For a Nautical theme, use navy blue, bright white, and bright red. If you want an Under the Sea look, go for soft blues, coral colors, and sandy shades. Select a calendar design that matches your theme, such as sailboats for the surface or watercolor octopuses and whales for the deep sea.
2. Create a "Coastal" Display
Display your calendar in a white wood frame or a silver frame. Add natural touches like seashells, a piece of driftwood, or a thick rope wrapped around the base of your table. Place a sign nearby that says: 'A new little matey is joining the crew! Cast your anchor on the date you think they'll arrive.'
3. Treasures from the Deep (Prizes)
Give your guests a prize they will be excited about! A sea-salt scented candle, a beach tote bag, or a nice salt scrub all fit the theme and are thoughtful. For a fun touch, a box of 'Saltwater Taffy' is a perfect 'message in a bottle' style gift.
