I started with Olfa cutting mats and Omnigrid (now Omnigrip) rulers and stay that way. i do have one Creative grid ruler i think. maybe two. one i know is very long with a lip on one end. i used that when cutting black out fabric for the back of some curtains. otherwise, it's just hanging in my sewing room.
i love square rulers, my 8x24 ruler and 12x8 one (think that is the right measurement). close enough anyway to get the idea. i also got recently the 20 inch ruler. it has side and corner triangle measurements on it for on point block design.
