The 12" x 18” A3 Cutting Mat by Cherry is really nice. It's double-sided, self-healing, and has lots of measurements and shapes. This mat is perfect for crafts of any kind except ones that involve heat. As a seamstress and someone who does a lot of cutting and measurements, this mat simplifies measuring and making things square. Overall, This mat is made well, looks and feels high quality, and provides a ton of useful measurements. The mat itself is nice and thick. The mat is truly self-healing too, prefect for rotary cutting. Something that really caught my attention was that there were claims of it being odor free. Since I suffer with multiple chemical sensitivity I was really excited since most mats stink really bad, especially when new. However, my hopes were completely dashed the first time I opened it. It definitely smells like plastic. Which would probably be fine for normal folks, but I did react.
All in all this is a really nice cutting mat. It is super convenient to have, it simplifies crafting, it looks nice, it's made well, and it works as described! If you're interested check it out in the link below:
