How do the stars make dried flowers?

1. Brief introduction of natural air drying.

This method does not require the use of any machines, so it is very simple. Time: we need to avoid the Meiyu weather. Specific method: hang the flowers upside down in the dry air. Be careful to stagger them so as to maintain the shape of the flowers and prevent them from colliding and deforming. After a period of time, we need to determine whether it has been air-dried according to the wetness of the air and the specific shape of the flowers. If you see that the shape is already very good, then even if it is done, you can insert them into the bottle.

2. Brief introduction of book pressing and air drying.

This method is also relatively simple, just like making plant specimens. Tools: a book (thicker) and cardboard. Specific method: branch the flowers and make them as small as possible. After dividing up, arrange the flowers in the book, and then close the book. If you are afraid of getting the pages dirty, you can put a layer of paper towels on them. After about three or four days, we can find that the flowers in the book have dried and flattened. They can be framed and used as murals.

3. Brief introduction of heating air drying method

The principle of this method is similar to that of the second method, but it will be faster in time. Specific method: first press the flowers with a card, and then put the cards and flowers on another piece of cardboard. Fix them with a rubber band and send them into the microwave oven. The waiting time should not be too long, usually ten seconds to half a minute. After taking it out, take off the card. Wait for the natural cool, then take the flowers out.
