Zip ties can help you create professional-looking floral arrangements with ease. To make a bouquet for a vase, simply stand up all the flowers and loosely loop a couple of ties around the stems. Once you have the blossoms arranged in a pleasing manner, tighten the zip ties to keep them in place. (Be sure not to over-tighten. You don’t want the ties to cut into the stems.) Then just place the arrangement in a vase for the decorative finish.
