To say "I love you" in American Sign Language (ASL), there are a few different ways to sign it, but the most common way is to follow these steps:

1. Make an "L" shape with your thumb and index finger.
2. Keep your middle and ring fingers touching your palm.
3. Lift your little finger.
4. Direct your hand towards the person you are talking to.

Another way to sign "I love you" is to point to your chest, cross your arms in front of your chest to make an "X," and then point towards the person you are saying "I love you" to.
