You have more control over the fabric, because the whole ruler is holding down the fabric, and if you cut the first cut and then remove the scrap part, the rest will hold steady by the slot. You can cut more than one strip without moving the ruler, plus you can cut several layers without slippage, something I always have difficulty with with a regular ruler.
