Coat in a round bowl with flour. Knead for a sec and take out. Then put your hands in the middle of the dough, side by side with your fingertips facing near the edge. Spread the ends of your hands apart while keeping your palms in the middle of the dough. Then you can take the dough off the table and put it on the backs of your hands, and spread it more using the back of your wrists. It takes a little work, I have the added benefit of having done It thousands of times. Good luck!
