I have a buffet that I painted and put in the outdoor courtyard of my home. I like to have it decorated with inexpensive seasonal items. As it is somewhat exposed to the elements I don't want to put anything of real value on it, so I use dollar store frames and free graphics. It takes just a few minutes to print out images. I love the "gather here with grateful hearts" printable from http://craftily-ever-after.blogspot.com/. I combined it with some vintage Thanksgiving art from http://graphicsfairy.blogspot.com/. If you would like to add some Thanksgiving cheer to your home (but don't want to invest any money with the holidays approaching), try printing out some of the great free online graphics and putting them into frames you already own.
