The main centerpiece is, of course, my seashells on a wire cake stand under a dome. I used this same piece in my Seaside Summer Memories Vignette. I love all the shapes and textures that are represented.
Finally, each place setting is punctuated with a seashell wrapped with jute twine and tied with a simple knot. Believe it or not, I got these cream damask placemats for about $2.50 for all four of them at Target after Christmas. I just love their "clearance" items!
