I wish the mat was just about an inch bigger. I was ironing 12.5 inch finished blocks over the weekend and had to keep moving the blocks around. 12.5 is a common finished size for a block so I find it kind of odd they didnt make a mat to accomodate that size. I am going to see how well I get along with the current size. I may have to order a 2nd one just to create a larger ironing surface.
flora516that's really a great point... may other product manufacturers who do a 12" size have figured that out and made their products 13" (like my rotating cutting mat)
