If you problem is that your ruler is slipping, you can use some Elmer's glue & add some squares of sandpaper to the back side of the ruler to help hold it in place. I did this & it helps alot. My main ruler is 6 1/2" X 24' & I use it to cut thin strips all the time. I got the sandpaper tip from Rhonda here on the board. She uses sandpaper on all her rulers.
