The cloth pad is an essential tool for the tandoor oven. Most users can use a glove along with the gaddi if you are not used to doing it with bare hands.
 
Just place the flattened dough on the gaddi and it shall help you place the naan bread or other breads.
 
Slapping is the technique to get the flat dough stuck to the hot side walls of the tandoor.
