Query: Signing Naturally 2

Signing Naturally are very good textbooks for the beginner and intermediate sign language students. The demo signing is a little fast for someone that is still learning, but the speed can be slowed down if you have a DVD player with that capacity. I am a student at college learning sign by using these textbooks.These are truly a must if you're dedicated to learning sign language and something about the deaf culture.
