Place two fingers in the large hole and your thumb in the small hole closest to you. Hold the paper with your non-cutting or helping hand with your thumb facing up. This increases the control you have over the paper. Always have the scissors facing with the thumb on top as seen here. Open the scissors by pulling the fingers apart. Place the paper where you would like to cut. When ready, close your fingers together. Continue to open your fingers, move the paper, and close your fingers. When cutting squares or circles, if you are right-handed move the paper with your helping away from you.
