Just flip that puppy over and use your ruler to measure. Far more accurate, in my opinion, that the lines on the front which I never use anyhow.

I'm surprised the mats aren't accurate, though I don't use for cutting the patchwork. I think it is better to know how to use your rulers to cut the shapes you want. More accurate. When cutting confusing shapes those lines just confuse matters even more. I always teach to use the side with no lines.

Like almost everyone I use both sides of my mat. But the unmarked side is where I cut my curved pieces and such as it can be difficult to cut when you do your circles on the same side as your straight cutting.

I find the lines on the mat and the lines on the ruler too confusing for my brain so I always use the back.
The thing you need to remember when cutting with a ruler and no lines is that the amount you want to measure and cut is under the mat. It feels odd at first and may be what the video explains. If you want a 2 1/2 inch strip, 2 1/2 inches is under the mat with the edge lined up with that line. |

My omnigrids are very accurate. I use the lines all the time. I am backwards in the way I use the ruler, can't do it the way they say. I have had no problems at all. I do know that they do sell mats that are not accurate. Just measure the mats and see if they are or not.

From my first lesson my teacher told me to ignore the lines, as I'm a good girl, that's what I've done ever since.

I'm not sure that 'inaccurate' is the best term for describing the lines on the mats. It - at least in my mind - goes to the principle of using the same ruler (or at least same brand) throughout your project. Not all rulers are created equal although you would think an inch is an inch is an inch. Just check the measurements on your different brand rulers and compare them with the lines on your mat. You'll see that you have slight variations between brands. If you're using an omni grid mat and omni grid ruler they are likely the same or very close. But different brands can be different. Plus the lines on the mats are generally thicker than those on your ruler which could also account for slight differences.
