[This is a Sponsored Post] - Sand dollars, seashells and starfish for crafts and weddings. Sand Dollars features information on sea shells and staffish for crafts and occasions such as weddings. I find some shells absolutely beautiful and amazing to look at. This site has a blog about all of the different types. Take a look at the Pearl Nautilus Seashell ; "The pearl nautilus outgrows its chamber and builds another a little larger and directly on top of its existing chamber and moves in to new chamber when built." Its a shell of a site (sorry) and well worth a look!
