I have used my cutting mat for over 15 years and was thinking that I needed to get a new one. Then I saw on a F&P video that you could turn it over and use the other side. Voila! A brand new side. Mine does not have the lines on that side but I never used them that much anyhow as I use my ruler more. Just an idea to maybe give you a bit more life from yours. Mine still had the sticker on the back side which clearly stated that both sides could be used!!
