Collect vases to use as the base for the birch vases. Vases that have shapes with smooth sides and that have the same width throughout the length of the vase, such as squares, rectangles and cylinders, will be easiest to cover in birch.
Apply vertical lines of hot glue over the entire surface of the vase. Before the glue dries, carefully wrap the birch around the outside of the vase, pressing it into the glue. Use a craft knife to trim any bark that overlaps.
Add some decorations. While a birch vase looks beautiful on its own, a satin ribbon or sash of lace tied around the vase is a simple way to add a feminine, colorful decoration. Glue some peacock feathers to the vase for a sophisticated look. For a delicate yet natural decoration, glue some silk leaves to the vase.
