Don't worry if the dough doesn't turn out exactly as you had planned.
Variety is part of the fun of cooking from scratch.
Stir until uniform. Continue adding flour, exchanging the spoon for your hands when the mixture becomes to difficult to stir. When first turned out onto the board, the dough will be rather sticky. Turn it over, push it with the heels of your hands and turn it over again to coat with flour. Reflour the board if necessary.
