Flower pressing is a technique used to preserve flowers and plants by flattening them between two surfaces, usually paper or cardboard. This process removes moisture, allowing the flowers to maintain their shape and color over time. It is a popular method for creating decorative art, bookmarks, and keepsakes. To press flowers, you typically place them between sheets of absorbent paper and apply weight on top. After a few weeks, the flowers will be dried and ready for use. Herbarium collections often utilize this method to document plant species for scientific study.
