[QUOTE=quiltingtrish;345474]Sherry, I have done and still do what you are doing. I use the mat to line up my fabric and cut using the ruler to keep a straight edge. I guess I use both cause I do use the ruler too. Anyways, if you use just the mat to measure, I was told to always use the same mat for the entire project because the mats can differ in sizes.

Yes, I think I have been doing it this way too. I have the same measuring tape that I use as well. My ruler and mat are both fiskars and I have been using them together since Nov 2012. Everything seems to turn out ok unless I calculate math wrong... Which I often do.. Lol
