To dry flowers, you can try the air-drying method. First, gather your flowers and remove any excess leaves. Bundle the flowers together with a rubber band and hang them upside down in a dark, dry place with good air circulation. Let the flowers dry for about 2-3 weeks until they are completely dry. Alternatively, you can use a drying agent like silica gel to dry the flowers more quickly. Simply bury the flowers in the drying agent and wait for a few days until they are dry.
