I was born in El Salvador, where back in the 80's there were NO Japanese. In one of my father's trips abroad, he brought back chopsticks for me and my brother that came with the instructional diagrams for how to use chopsticks. I have drawn these diagrams demonstrating the technique I learnt. If a 6 year old Salvadorean can learn, so can you.
P.S. My parents lived in Korea for about 8 years and I worked in Tokyo, and the technique I learnt when I was 6 proved to be the proper way, so give it a shot and impress your friends on your next sushi outing.)
NOTE: The further up you hold the sticks, the more elegant it is.
