When prom night is over there is no reason to throw out the flowers. They can be dried and used as a floral arrangement. If you intend to dry the flowers, don't keep them in the refrigerator after prom night, but dry immediately. Left in the refrigerator they will eventually begin to wilt, which will produce an inferior dried corsage. The prom flowers can be air dried or dried with a desiccant material, such as silica gel or a borax mixture.
Select a box that is slightly larger than the prom flowers. If using silica gel instead of a borax mixture, the box must have a lid and be airtight.
Pour 1 or 2 inches of desiccant material into the bottom of the box. You can use silica gel or a mixture of equal parts borax and white cornmeal, with 3 tbsp. of non-iodized salt added to each quart of the borax mixture.
Set the prom flowers into the mixture.
Cover the flowers with the desiccant material, so that they are entirely covered. Jiggle the box slightly to remove air pockets, and cover with more desiccant material, if any portion of the prom flowers are exposed.
Store the box in a warm, dry location. If using silica gel, the box must be covered with an airtight lid; if using the borax mixture, leave the box uncovered. It will take three to eight days to dry using silica gel and two to three weeks if using the borax mixture, depending on humidity factors.
Attach the prom flowers to a clothes hanger, using a clothespin. Hang the flowers upside down.
Hang the clothes hanger in a dry, warm area out of direct sunlight. Choose a well-ventilated area and don't allow the flowers to touch anything while they are hanging.
Allow the flowers to dry for two to three weeks.
