It's hard to get a good, full cut without creasing the mat, but you can minimize the creasing. Read this blog on how to properly adjust blade depth. Make test cuts for every material you use and create your own cut settings. But even these settings will not always work, since the blade will gradually dull. You will have to do further adjustments. If the mat is cut through in places, you can still salvage it by taping cut throughs from the underside with painters tape or vinyl scraps. Mats are consumables. I have a stock of about 20 mats at any given moment. If you are in the States, these mats are very affordable and they are good quality. Otherwise, consider ordering off brand Silhouette mats elsewhere online. Make a habit of working with several mats with different level of stickiness. Use brand new mat to cut large and simple shapes, because new mats are very sticky. After it lost some stickiness, use it for intricate cuts. Start using another mat for simple and large cuts and so on. Once you have variety of stickiness, use the mat that best suits what you cut. You can also reduce mat stickiness by tapping it with lint free cloth, denim, your hands and what not.
