This one is the one most of the women in my Quilt Group use. Although when someones Mat is already set up we all may use it and usually do.

This one is a little bit smaller than mine and maybe easier to handle.

This one is mine the size I prefer although if you carry it very far I suggest another size one smaller and easier to handle.

As you can see there are lines and Numbers that you can use when you are cutting, not everyone does it this way but I do.
