Cut wooden dowel in half and form into the shape of a cross, securing pieces together with hot glue.
Cut a second wooden dowel into halves and secure pieces onto cross formation to form a five-pointed star shape (the bottom dowel will serve as the stand for securing to the top of the tree).
Following the star shape as a guide, stack driftwood sticks onto the wooden dowels and secure each piece into place with hot glue, to widen the points of the star. (Tip: We used 2-3 layers of driftwood sticks for a multi-dimensional look.)
Hot-glue seashells onto driftwood star as accent pieces, starting with the larger sizes, followed by medium-size ones, then adding accents and filling in holes with the smallest ones. Let dry completely before attaching to treetop with wire.
