It is so much fun to change the little things. When you put flowers in that old glass bottle, the one you almost threw away, or the one that collects dust on a shelf; let it add style to the table. Mix and match. Play around!
If you don't have one sitting around, you can look for them at yard sales, thrift stores, flea markets, or you can buy a new one at the grocery store :). After a little cleaning out they are good to go! What I think adds fun to the mix is matching them with flowers that accent them well. Color block, color blend, or match exactly.
They really are beautiful placed around your house.
