After your homemade flour tortillas dough has rested, divide it into 8 equal sized balls.
Flatten them with a tortilla press. If you don't have a tortilla press, roll it out on a cutting board until very thin. Getting it very thin is tricky, but the tortillas are so much better if the dough is thin.
I use all-purpose flour in my homemade flour tortillas, but you can use other types. Alternatives will be listed below.
