Remove one or both of the dough disks from the refrigerator onto lightly floured work surface, and let sit at room temperature for 5 minutes or more as needed. (When the dough first comes out of the refrigerator it can be stiff, making it hard to roll out. Leave it on the counter for a few minutes to warm up slightly, then try rolling it out again.)
Flour the surface of a rolling pin and the top of the dough, and roll dough into a 12 inch circle. Add flour as necessary to make sure the dough isn't sticking to the surface or rolling pin. Crust should be about 1/8 inch thick.
Transfer dough into pie dish, with about 1 inch overlap around the edges of the dish.
Gently press the dough down all around the inside of the dish
Trim the edges of the dough with a knife all of the way
If making a single pie crust gently press the edges with 2 fingers all of the way around to give it a crimped look. Place crust in the refrigerator for 20 min.
If making a pie with a double crust, fill crust and add the top crust then trim and crimp edges.
Bake according to pie recipe.
