I don't consciously use just one Mfgrs rulers, or cutting mats, however it turns out my favorites, most used are all from teh same Mfgr. The only time I use somethinng else is when the preferred Mfgrs does not have the tool I need. Gues I am an equal opportunity quilter, HOWEVER. I do make sure that they are cutting the same measurement if not they are history.
