I love that items and elements from "life on the shore" are becoming popular touches in interior design. Keep your eye out and I think you will notice this more and more.
Framed shell images, heavy white "coral" pieces for display on a bookshelf, even shells themselves to fill a vase or arrange on a table.
My weakness is shell-covered boxes - I practically have a collection by now and I think that they are gorgeous! I'll photograph one soon to show you.
The next time you are looking for something to add interest to your living room...go to the coast.
