When using a microwave for drying purposes, use a desiccant such as silica gel to support the flowers in a glass or microwave-safe container. Do not cover the container, and always place a cup of water in the oven before beginning to prevent excess drying. Drying times vary, and a standing period following drying is necessary to complete drying and allow for cooling. When using the upside down method of drying, prepare the place where flowers are to hang. Since they must be dried quickly, a dim attic with good air circulation is ideal.
Most basements are too damp, and closests have too little air circulation.
To prepare the area, string wires or cords in parallel lines, about six inches apart. All foliage should then be stripped from the flower stems and the smaller flowers tied in bunches with differing stem lengths, so that the flower heads do not touch each other. Large flowers should be tied individually. The bunches and individual flowers should then be fastened to the strung lines, far enough apart so they do not touch.
