There are two ways you can transfer the dough from the counter to the pie pan:
Place the rolling pin at the top of the dough circle. Gently roll the dough over the rolling pin towards you. Use the rolling pin to transfer the dough to the pie pan and gently unroll it to set it in place. My mom used to fold the dough in half, then in quarters. Use a dough blade to gently loosen any places that are stuck to your counter as you go. Once folded in quarters, you can lift it into the pie plate, unfolding it to set it into place.
