This is a simple rectangle with negative embossed measurements for ¼" and ¾". the idea is that when you want to roll out cookie dough, but don't have a rolling pin with the spacer wheels, or you don't want to use the paint-stick / chopstick method of setting the rolling pin at a certain height. This design is printed twice ( laid diagonal on a 220x220 bed to get maximum length ) and placed down in either thin (¼") or thick (¾") orientation ( embossed measurements face upwards ) then you can roll out the item and be sure it is uniform in it's thickness, good for making cookies, or rolling out mince for home-made nuggets / burgers.
