All you have to do is line a cookie sheet or pan with the mat and place dough into the 15 equidistant sized rings to make consistent, delicious treats.  The Baking Mat also has central rings that provide you the measurements for bigger sizes from 3 inch to 9 inch.    They are also ideal for healthy cooking: use a mat without added cooking oils, butter or sprays to save on calories and fat.  Each mat is oven safe for up to 400°.   Wash mats before use.  Wipe clean with a soft, damp cloth after each use.  Store flat or rolled.  Measurement: 16. 5 inch x 11. 6 inch (42 cm x 29. 5 cm).  Weight: 4. 3 oz
