I liked the smaller cutting mats. I have used it for meats, veggies, and even Kalen took one and used it as a coloring mat. The mats also have lines for measuring. You have numbers along the side, plus the dotted squares in the middle. I use them when needed and store them back in my kitchen tools bin in my room. My tools don't go downstairs to the kitchen with everything else :-).
You can purchase the mats on Amazon. They come in a set of 4 in 4 different colors. The mats are prime-eligible.
