Dried flowers are used in craft projects, such as framed floral pictures or in decorating greeting cards and scrapbooks. Several ways exist to dry flowers, such as air drying, using a desiccant or freeze drying. After drying a batch of flowers it may be a while before you use them all, which means they must be stored properly. Bugs and insects can get into the dry flowers, causing damage. Even if stored properly, they won't last indefinitely.
Spray the flowers with a clear plastic spray that doesn't contain water. This will help preserve the flowers by keeping moisture out and keep dust from sticking to their surfaces. Cans of plastic spray finish, which can be used on dried flowers, are sold at craft stores. Apply according to the manufacturer's instruction of the can you choose. Some people choose not to spray their flowers prior to preserving (due to personal preference) so this step is optional.
Lay a sheet of tissue paper on the bottom of a box. Choose any box that has an airtight lid, such as a plastic container or metal box.
Arrange the dried flowers on the tissue paper, in a single layer without overlapping. Avoid having the flowers touch, to prevent damaging the fragile flowers.
Cover the dried flowers with another sheet of tissue paper and add another layer of flowers, if desired. Continue adding dried flowers, separating each layer with a sheet of tissue paper.
Seal the box with an airtight lid.
Store the container in a dark, dry location.
Check periodically, to make sure bugs and insects haven't gotten into the box. Insects might get into an airtight box if the lid has been disrupted or insects were initially on the paper or flowers and went unnoticed.
