Same thing happened to my creative grid 2 1/2 x 6 1/2 ruler (love that thing). I searched and searched for a month, finally resorted to cleaning and reorganizing the bloody room -- still no ruler. A couple of weeks later, I got up early and went into my sewing room to put something away. You guessed it, there is my ruler laying in the middle of the floor. I had just been in there the previous night -- no ruler.
