To make these dynamic table centerpieces, simply arrange tall birch twigs, sweet annie, and peacock feathers in a glass container or crock.  Materials were gathered from the surrounding fields of my property and the peacock feathers were given to me by a friend.  I choose black opaque containers to pull in darker tones from the leather chair and large ceramic pot (seen at right in above picture).  Display eclectic pieces, like sunflower heads, grains, or geodes, around centerpieces for a relaxed feel.
