You can press the dough with your fingertips to stretch it out.  Don't press too much to the edges so you can create a rim. Pinch the edges by placing your hands inside and outside of the dough's edge to create a rim. You don't need a rolling pin; you can use your hands to roll out the dough as long as you don't want to make a paper-thin crust.  How to freeze the pizza dough After you make balls out of the dough, cover each dough with parchment paper and place them in a ziplock bag. Thaw overnight in the fridge before using them. Roll out and top as you like. If you'll use the dough in 2 days, instead of freezing, you can keep the pizza dough in the fridge as well.
