How to sign

To sign "Interest" in American Sign Language (ASL), form a fist with your non-dominant hand and hold it steady in front of your chest. Extend your pinky finger from your dominant hand while keeping the other fingers folded down. Touch the top of your non-dominant hand's fist with the tip of your dominant hand's pinky finger. Then, make a small circular motion with the pinky finger, as if tracing a small circle on the top of your fist.
