A fuller look can be achieved starting with flower stems that have multiple blooms per stem, such as asiatic or oriental lilies, or that have a larger presence, such as hydrangea. The sheer number of stems also provides a very full looking arrangement. For a fuller look on a budget, you can ask for mid-range or cost-effective flowers, such as alstroemeria, stock, any seasonal specials, or even colorful foliage textures.
