Whether your fabric is textured or flat, you can be assured your cut line is on point. – Place fabric on the cutting board. – Turn on your Nifty Notions laser and place it all at the start end of your cutting line. – Target the laser light to the desired endpoint. – From that endpoint, place scissors at the cutline so you are facing the laser level device. With the tip of the scissors and proceed to cut across the red laser cutting line projected from the Nifty Notions Laser. Stay along the line and cut with confidence!
