Materials: tin foil paper, double-sided adhesive
Steps:
1. Fold the tin foil in half and cut out a semicircle with reaming shears. Then cut a small semicircle in the central section and open it to form a circle.
2. Cut some double-sided tape and stick it in the lampshade. In order to operate easily, you can remove the light bulb first, and then paste the just cut tin foil in the lampshade.
