Chalk dust ruins light carpets every time. I use a metal straight edge and a sharp pencil for exact lines. A quick wipe with a damp cloth removes the marks after cutting. Your method saves time and keeps the work clean.

That contractor's infected drive story is familiar. A friend at a logistics firm saw something similar when an employee used a personal thumb drive to share a report. It introduced ransomware that locked up their order system for a day. They ended up banning all personal drives and now provide company-issued, encrypted ones for rare cases when they're needed. The mess it caused made the security team's point for them.
