Start off by holding the first chopstick. This one is supposed to be held between your thumb and your middle finger. You must position the stick in such a way that the stick falls on the base of your thumb (joint) and use the lower joint of the middle finger to grab the stick. Whatever you do, make sure that this chopstick does not touch your forefinger.
Now it’s time for you to hold the second chopstick in the perfect manner. While holding the first chopstick, grab the second chopstick between your thumb and your forefinger. Make sure that the side of the chopstick is resting right at the tip of your thumb. On the other side, the pad of your forefinger is going to help you grab the chopstick.
Once you know how to grab a chopstick, you just need to make sure that the tips of both the chopsticks which you are holding are parallel to each other. This means that there is a little gab between both the chopsticks, so you can grab food with it.
Now, in order to practice, simply start moving the chopstick which is held between your thumb and your forefinger. This means that the other chopstick remains still and stationary, while the other chopstick is moving up and down like a jaw.
Now use the same technique over a food item and try to grab it.
Once you take hold of the food, grab it firmly and move it towards your mouth in order to eat it.
