1. Pick branches when fall leaves are in their prime and immediately place stems in water.
  2. Boil one part liquid glycerin (available in pharmacies) and two parts water 6 for 10 minutes. Let cool.
  3. Remove branches from water. Pick off any curled or damaged leaves.
  4. To increase absorption of the glycerin solution, mash the stems with a hammer, or use a sharp knife to cut length-wise slits in the stems. Stand stems in solution and set     container in a cool, dark place.
  5. After a few weeks, the solution will be absorbed and you’ll feel it on the leaves. Remove branches from the solution and wipe leaves with a soft cloth. Colors will deepen a bit over time.
  6. Treated with a glycerin solution, leaves remain bright and supple for several seasons. Arrange full branches in a vase, or scatter single leaves artfully across a tabletop.
