Clover Cutting Mat - 18" x 24" Clover got it right with their cutting mat. This self-healing mat is not the same as other mats. Clover incorporated some great, practical features that make theirs unique. For starters, they've used a soft green color that is easy on the eyes. And, not only do they have extended gridlines, they have the numbers marking inches on the outside edge of the grid so they are visible even when your fabric is right up to the edge of the grid. To top it off, it has a hanging tab for easy storage and to prevent warping. What more can you ask for?
