The size of this mat is perfect for cutting 12x12 papers. The extra inch on the sides makes matching up the measurements easy. I love this mat.
Love, love, love this mat! The larger size is perfect for cutting 12x12 paper, the lines are bold and easy to see, heals up nicely. And when you're not using it, flip it to the damask side and it pretties up your craft space. It's my new favorite mat!
