Review on Large Double Sided 5-Layer Gridded Green/Black PVC Cut Mat for Sewing, Quilting, Scrapbooking, Arts and Crafts - WORKLION Self Healing Cutting Mat, 24 x 36 inch by Kelsey Brown

Received today and I am not happy with the camper. I didn't look closely at the picture of the A3 mat. The size of an A3 mat is 17 inches on the bottom and 11 inches on the sides. How do you describe it as 18 x 12? Even accounting for the unmarked green border, it still doesn't measure 18 x 12. Apparently, it has the same problem with the blue side as it does in the metric system - it's also too short. This is clearly false advertising, even if unintentional. Why didn't they measure the way they should i.e. How difficult was it for them to make a mat marked 18" and 12"? Markings aside, the mat is fairly thick, is described as self-healing, and has imperial measurements on the green side and metric measurements on the blue side. It will probably be sent back and the search for a great carpet continues.
