First I put a new blade in my utility knife and got out my metal square to use as a guide. I put a piece of thin wood under the plastic where I would be scoring.
I made my measurements and markings and drew a line where I wanted to break the plastic.
Then I made several scores on the line with the knife carefully holding my fingers out of the way in case the knife slipped and jumped over the metal guide and sliced my fingers.
When I was scoring glass, I would make several light passes with the knife to make a deep score instead of one heavy one so there was less chance of me losing control and doing myself damage or going off the line.
After I had the line scored, I aligned the plastic sheet so the scored line was just over the edge of the table. Then I leaned one arm down on the plastic on the table to hold it secure and I pushed down with my other hand on the piece hanging out until it broke along the line.
I guess I was lucky it broke cleanly. When cutting glass you tap along the scored line to make small fractures so when you break the glass it breaks along the line.
Doesn't that look nice and neat with the plastic under the keyboard and monitor.
Yikes! This is the stuff I moved that was behind the monitor and along the side counter. I'm going to empty the drawers and sort through all this stuff and hopefully get rid of most of it.
I painted most of another wall today. The upper reaches of the wall will have to wait until Sunday or Monday when I can get some help holding the ladder.
I wonder if it would have stopped again this year
