Is It Time to Replace My Cutting Mat?
I have a 36" x 24" Olfa cutting mat that I've been using for the past three years. It now has grooves worn on the most common lines that I use to cut on - those that are 2.5 inches apart. I've turned the board upside down and worked from the opposite end, but the grooves are everywhere now. I do use the other side (the side without the lines) when I'm squaring up or cutting something that I only need a ruler to measure.
The grooves do not seem to megatively impact the accuracy of my cuts. Is it time for me to get a new mat? If not, what criteria do you use to determine when to replace your mat?
