Lighthouses, Sailboats and Sand Dollar Cookies

For my Farmers' Market table each week I come up with a theme.  Three or four cookies that link together somehow makes for a lovely table.  This week, I was inspired by the heat of summer.  Where would I like to be to get away from the humid Ontario air (and the heat made by my oven!)?  Something nautical came to mind and that's how I ended up with lighthouses, sailboats and sand dollars.  And they were a hit!  Happy summer!
