I make my own crusts in the food processor, but I've discovered that the Walmart Great Value refrigerated crusts are excellent and easy to work with. When you take them out of the fridge, stick them in the microwave for a just few seconds so they're pliable. Always start by placing the crust evenly in the center of the pie plate. Wet your fingers to make shapes.
Beginner: After folding the edge under as directed, use a spoon to press a design into the rim of the crust.
Classic: Fold edge under. Place your thumb against the inside rim of the pastry; press dough around thumb with your other hand's thumb and index finger.
Edge Circles: Trim pastry flush to the edge of the pie plate. With a melon baller or a small cookie cutter, cut small circles from pastry scraps. Use a little water to attach circles around the edge.
Scalloped: Fold edge under as directed. Loosely pinch dough around your thumb to form scallops. Use the tip of a spoon to make indentations in the inside of the scallop.
