Cricut Adhesive Cutting Mats
These mats are a critical component of the Cricut Cutting Machine – they hold the material that you are cutting in position while the machine is making the cuts. There are several different mats, depending on the machine you are using, the size of the material you are wanting to cut, and the amount of hold that you wish for the mat to exert on item that you are cutting.
This second one is twice the length, and I find that it is very helpful if I am creating a cut that I want to go across the full width of the double spread. I put two 12×12 sheets on it, make the cut, and then it is already cut for the split in the double spread.
