I recommend the following five ways to turn waste into treasure:

1. Make decorative paintings: Use discarded buttons to make simple and beautiful decorative paintings.

2. Make a decorative box: Decorate the shoe box with wrapping paper or paint, and decorate the interior according to personal preferences.

3. Make paper cup decorations: Transform disposable paper cups, such as cutting out small animal-shaped cardboard and pasting it on.

4. Make small rockets: Use instant coffee bags to make rockets and add other small decorations.

5. Make toys: Use waste materials such as egg trays, egg shells, paper clips, paper cores, etc. to make toys such as sailboats and racing cars.
