Place the stems in a vase with a few inches of water in it, with a couple drops of bleach.
As the water is drawn up into the stems and the water evaporates, the flowers will dry naturally. Hydrangeas are the only flowers that I know of which dry in this manner.
I've also read that adding glycerin to the water in the vase will help with making the dried flowers more stable and longer-lasting.
Hang on anindoor clotesline set up, upsde down. When dry, spray with a fixative from the craftstore so they won't loose their flowers
