How simple and inexpensive can this DIY project be? Austin Wedding Blog uses an assortment of colors of cherries, go red, or golden, make small 'flags' to put around the stems and use your computer to type names on them in a cursive font before you cut them out and glue them around the stems of the cherries. Do the same to put the 'table number' on each cherry. Put the number of cherries on the saucer of the people sitting at the table plus one.
Choose a pretty saucer for a romantic garden party look. Either pick up saucers from friends and family or hit Goodwill or the your local garage sales. Inexpensive but pretty! (Not to mention edible!)
Be sure to take some time to browse through this blog, it's full of great ideas that aren't too hard to execute.
