As an experienced lighting expert, let me tell you the process of cutting the plastic lampshade

★Gather Your Tools: You will need a sharp utility knife, a straight edge or ruler, a pencil or marker for marking the cut line, and safety gloves to protect your hands.
★Clean the Plastic: Keep the plastic cover clean to prevent the knife from slipping
★Measure and Mark: Accurately measure the area that needs to be cut and mark the cutting line with a marker
★Secure the Light Cover: Place the plastic lampshade on a stable surface and secure it with something heavy to prevent it from moving during cutting.
★Score the Plastic: Use the utility knife to lightly score the plastic along the marked line. This scoring will guide your cutting and help prevent the plastic from cracking.
★Begin Cutting: Hold the utility knife at a slight angle to the plastic and start cutting along the scored line. Apply steady pressure and move the knife slowly to avoid slipping.
★Cut with Care: As plastic is fragile, it is important to ensure a clean cut. If the plastic is particularly thick, you may need to make multiple cuts along the same line.
★Smooth the Edges: After cutting, use sandpaper or a file to smooth any rough or sharp edges.
★Test the Fit: Before fully committing to the cut, test fit the piece to ensure it fits properly.
★Finishing Touches: Use plastic polish or sealer to polish the edges for a professional look
