One of our favorite ways to arrange flowers is to split up a bouquet into a cluster of vases. It makes for a loose, unpretentious arrangement... Gather clustered vases together on a mantlepiece, in the center of a table, on a credenza, or on an end table. It's best to use vases of varying heights to get an arrangement that looks relaxed without seeming awkward. One of the benefits of arranging flowers this way is that you can use just about anything for a vase. Click here for a list of household objects that double as vases. Image via Real Simple.
