What you needBunch of roses
To dry roses naturally , wait till your bunch of roses open completely then remove any dried broken or brown leaves from the bunch.
Using some elastic bands or garbage bag ties secure the stems into a bunch.
Using some string attach it to the bunch of roses and hang them up in an area with non direct sunlight.
Try to have them hanging directly upside down or you may find your roses dry on a wilting angle.
Once the roses are fully dried spray them with some normal hairspray. This gives them a fine lacquered coating that will keep the dust off them.
