(Quick & Inexpensive) Modern Flower Arrangement

It was 30 minutes until our dinner party and I still hadn't bought or arranged flowers. So I ran into our local grocery store and picked up an (inexpensive) bunch of purple dahlias. I split them into two arrangements - one long skinny vase held four standing flowers and I placed the rest in a rose bowl. I arranged the stems from the cut flowers in the center of the rose bowl arrangement to add some height (and saved money on greenery.) To keep the stems standing tall I loosely wrapped a clear hair band around them before placing them in the bowl. Ta Da! Two arrangements for about $5.
