I have used these mats for years so I recently purchased the 30ct knowing I would put them to good use. The very first piece of cardstock pulled up during my cut with the Maker. I tried and tried but it just wouldn't stick without using washi tape on the corners but even then my cuts in the middle of the paper would get wobbly. I tried 2 more mats and had the same problem. These are less sticky than the Light Grip mats.
