I am looking at pucchaseing my first cutting mat and would like to know what would be the best kind to purchasr. This will be going on a new table that i am building in my new shop in the next few months. I plan on building a 3' x 6' table and putting a 2' x 4' glass in the center for a light to be placed under it. I would like to place a cutting matt over the glass. Is this a good idea or not.
