I use two mats on the cutting table. They fit side by side and can be moved if needed. I line up the measurements and add some painters tape underneath. The tape keeps them in line. Generally, I'm not cutting more than across the WOF (approx 22 inches) so this works for me.
Be sure to check the marking lines as they vary between brands. Some are more user friendly. Some brands are short on the 24 side of mat.
