I just got mine that I ordered from JoAnn's. It is the 12 X 18 with 1/4" measure. I have the original one, the small 1/4" one and the half-square triangle one. This one has a 1/4" measure on the left and then 1/2" intervals the rest of the way. But you line up your fabric with the 1/4" line and then start cutting. I love it.
