Review on 🔪 US Art Supply 12" x 18" Green/Black Professional Self Healing Cutting Mat - Ideal for Scrapbooking, Quilting, Sewing, and All Arts & Crafts Projects by Dawn Fischer

The mat arrived bent. I'll have to let it warm up and put some weight on it to see if I can straighten it out. Also, the mesh is 11 x 17 inches, not 12 x 18 inches. Measurements less than 12" x 18" x ¼" on each side. More like 30 x 45 cm, actually 6 layers (I checked with the magnifying glass) but the mat says 5 layers. Must be a typo. : ). Center-to-center grid lines are accurate (1/100th of an inch is better). For this reason I give 3 out of 5 for accuracy. It would be 5 out of 5 if the grid lines were 12" x 18" but I think this is more of an error in the product description than an actual error in the printed lines I will check the strength as soon as possible Level it It does not slip It slides on hard surfaces It seems non-slip for some items on of the mat. It definitely doesn't glare which is nice. By price. 3 out of 5. You can get a Fiskers rug with true 18" x 24" grid lines if you need those gradations for something more.
