Roses are often given as tokens of love or to commemorate an occasion. Preserve your bloom through drying it. Roses lend themselves well to preservation through drying with silica. Look for this powdery material in craft stores.
Pour silica to a depth of 1 inch in the bottom of the airtight container.
Lay the rose on top of the silica, and shape it to how you want the petals to look after it dries.
Cover the rose with silica, paying close attention to getting the drying agent between the petals.
Seal the container and set it in a cool, dry spot for 36 to 48 hours or until the rose has completely dried.
Dust off the excess silica and keep your rose in a sealed, clear container in a low-humidity environment to prevent it from reabsorbing moisture from the air.
