Preserve flowers from a cherished bouquet or a piece of beautiful fall foliage with an iron and wax paper. First, sandwich the flowers between two sheets of wax paper, and then place a heavy book on top to flatten. While you wait, empty the water from the iron—you don't want any steam involved in this process. Replace the book with a paper towel, then press the iron over the material to seal. This process will act as a lamination for the flowers, allowing you to use them as decor or crafts for years to come.
