Designed by Jane Coslick, this kitchen is one of my all-time favorites! Adding the bright blue screen door to the pantry was a great way to bring in a bit of the beach.
An indoor/outdoor area rug will not only add a coastal feel, it will also hold up well under heavy foot traffic.
Grasscloth Wallpaper is a fairly inexpensive way to instantly add texture, reminiscent of sea oats. You can find faux grasscloth at most home improvement stores for even less than the real stuff.
Bedding covered in images that depict sea life is a great way to inject some of the beach onto your bed.
Wood counter tops, and exposed dishes scream beachside cottage.
Clad your walls in inexpensive bead board paneling (horizontally) to create a fresh, coastal look.
