Goal: Assemble some of the images below which use painted willow or birch branches.
First thoughts: Buy a quantity of willow branches and paint white. The bride-to be has found that Michaels craft store wants a high price for a very small quantity of branches. I have found this resource, which sells 40 to 50 stems of Curly Willow for $15 per bundle which sounds like a good deal. They also sell Mitsumata, Birch, and Manzanita stems. Once you soak the bundle they expand a bit and you can reshape them, meaning that as few as five may look perfectly fine at each table.

Other options: If for some reason, the willow does not work you can use any other kind of interesting shaped branch and attach decorative paper, felt cutouts, or already-created items.

Designer Angela Adams painted these red and attached purchased birds (as seen on the Rachael Ray website) or you can use feather butterflies from a craft store.
How about using a fairly heavy gauge wire and "hanging" kites from your branches or create groupings of brightly colored origami good luck cranes? So many possibilities...
