Curly Willow Branches Curly Willow makes a fabulous addition to any floral arrangement, centerpiece, or craft project. These branches are naturally twisted and are quite flexible. These versatile willow branches can be placed in floral frogs or styrofoam blocks in arrangements, or they can be tied or glued into place for whatever you are crafting. Dried willow branches can even be shaped for your specific needs. Simply soak the branches in warm water for a few hours until even the thickest portion of the stem becomes pliable. Then you can remove the willow branches from the water and gently bend them between your fingers to make your desired shape.
