Your invitations don’t need ocean wave artwork, sand-filled envelopes or glued-on seashells to convey that you’re having a beach wedding. Elegant beiges and blues signify sand and water, while wooden textures and rope embellishments can suggest boats and boardwalks. Do it yourself: Bride Natalie Mounier added dried, pressed blue-hydrangea blossoms and a bamboo mat backing to her letterpressed invitation. Total cost: about $8 per invite.
