I have several rulers. I really like the ones without so many markings. I have a 6" x 24" that is pretty much my go-to. I added a handle to the ruler and it makes it manageable in that it doesn't slip so much. I would wonder about a 8 1/2" wide ruler slipping around too much. My handle is one of those gripper type handles made to put in bathrooms but it works wonders. I bought it at Lowes or maybe Home Depot and is a lot cheaper than the same design that is made for quilters.
