Mason Jar Centerpieces - Easter Ideas Create a simple yet elegant centerpiece by using a bunch of vintage milk bottles to hold flowers aloft. Simply line up nine same-size vessels in three rows of three. Then wrap gardener's twine around the grouping twice and tie the ends. Finish the blooming display by placing two to three stems in each container. Smart idea: Separate the milk bottles and flowers afterwards to give to your guests as party favors.
