I nearly always use a scant 1/4 inch. Also, I tend to cut into the ruler just a slant, not so you would even notice. I have to really watch to keep the rotary cuttter straight in my hand. A teacher, when I was taking a class one time, told me some right handed people tend to push in and slant toward the ruler.
Hope all the suggestions help!
