Roses preserved with this method can be arranged in framed displays. This is the best method for a single rose. Heat Pressing Put a rose between two pieces of waxed paper and press the waxed paper with a medium hot iron. New pieces of waxed paper must by used for each rose. Cover with clear plastic to keep off the dust as they dry, but make lots of tiny holes for air circulation.
Roses lose color and shrink when air-dried.
Desiccants Bury the flowers in a granular, desiccating material. This can be purchased from craft stores or floral shops. The different types are Oolitic sand, silica gel, and borax. Glycerize Mash the end of each rose stem with a hammer. Put the stems in a warm mixture of glycerin water - 1 part glycerin to 2 parts water.
