How about filling your tall vases with vine clippings--with or without flowers. And there are several pages with photos of frugal finds. (I love the imitation croquet mallet plant markers, but how long will they last in the ground?) There are more great suggestions in the May 2013 issue of Country Living. There's also a good article on staging your yard sale, and I like the Lemon Ice paint color (subtle) from Benjamin Moore.
