It is best to hang flowers upside down and dry them first, but they can also be mailed fresh. The flowers can be cut off at the stems, so only the flower heads need to be mailed. Please wrap the flowers in tissue paper and mail them in a mailing bag, box or manila envelope. Make sure you do not put them in any saran wrap, bubble paper, or plastic baggie. This will cause your flowers to mold and therefore cannot be used. Remember, you can have flowers from over 50 years and still do this process. If your flowers have molded, they will not be able to be made into beads.
