I agree with Mazda, if the bloom is wired, it's isn't as successful. Silica Gel is a drying agent. You have to take the blooms off the stems, and dry them in a plastic shoe box. Layer silica gel on the bottom, then the blooms, then cover with silica gel. Labor intensive, but they look great. Then you use the blooms in an arrangement, like a shadow box with other memories, and have that as the keepsake.
If you want o dry the whole thing intact, I have heard that sometimes, depending on the flowers, hanging upside down can work. Maybe someone from the Disney Weddings can give other suggestions.
Congrats on your wedding!!
