Flat-faced flowers, such as pansies, daisies and petunias, are ideal blooms for pressing. For best results, start with fresh, well-hydrated blossoms. This method preserves the color and shape of blossoms the most effectively. Dry flowers can be pressed, but they are more brittle and prone to crumbling under pressure. Take care when handling dry flowers and hydrate them slightly before pressing them for the best results.
Cut away the stems of your dried flowers with sharp pruning shears. They will not press.
Coat dry flowers with a thin layer of glycerin to make them more pliable. Spray or brush the glycerin onto all parts of the flower. Allow it to dry completely.
Place the flower between two sheets of plastic. Plastic sandwich bags or non-cling plastic wrap both work well.
Insert the plastic-wrapped flower between the pages of a thick, hard-cover book. If you plant to press more than one flower per book, put at least 1/8 inch of pages between each flower and do not allow them to overlap.
Weigh the book down with bricks or more heavy books.
Leave the flower to press for two weeks.
