Beach-theme bridal shower decoration ideas please?

Where is this taking place? Because I live in New England and the store The Christmas Tree Shop is popular around here and they have TONS of beach decorations. You can also go to any craft store. They will always have sea shells and sand and funky gles you can use to decorate with. A popular ocean-y flower is a hydrangea. A nice little centerpiece idea is to get a few different size gl containers, put some colored pebbles at the bottom (found at a craft store), fill them with water and then put floating candles on top. You can also put a single stem rose in there, and secure it down with the pebbles.
