To preserve your bridal bouquet while retaining its three-dimensional shape, dry it in air, using desiccants, or in a microwave. Alternatively, use a flower press or books to dry the blooms separately.
When drying the bridal bouquet in air, hang it in an area that is dry, dark and warm, such as a infrequently used closet or attic for several weeks. If the bouquet has flowers with varying flower size and petal thickness, separate the blooms based on their size and petal thickness, and then hang them.
If using desiccants such as silica gel, borax and sand, layer a cardboard or plastic box's base with the drying agent, and lay the bouquet over it. Sprinkle more of the chemical over the bouquet, and leave it for about 10 days. Then, dust the chemical out of the bouquet.
When drying the bouquet in a microwave, take out the metal items in it, layer silica gel in a microwave dish to a depth of 1 inch, and lay the bouquet over it. Add some more silica gel on the petals of the flowers so that they are covered completely by the gel.
Then, place the dish in the microwave along with a cup of water, and microwave for 1 to 3 minutes on high. Use the trial and error method to determine the exact time for microwaving. Stand the bouquet in the microwave overnight or up to 36 hours.
When pressing the flowers in the bouquet, separate each flower, and take out its stem. Place the flowers on newspapers, leaving sufficient space between the flowers, and then keep the same between heavy books or a flower press for two to four weeks.
