Preheat the oven to 425 degrees.
Add cherry filling to the pie crust.
Roll out remaining dough 2 inches larger than the rim of the pie plate.
Use a heart cookie cutter to make a design in the middle of the crust (or use a fork to pierce holes in the center of the crust).
Drape the top crust over the pie. Trim the edges of the two crusts to 1/2 - 1 inch beyond. Fold the crust under and crimp the edges.
Bake the pie for 20 minutes and then lower the oven temperature to 375 degrees. Add tin foil around the edge of the crust to keep it from burning. Continue to bake for another 30-40 minutes until the juices start to bubble.
Remove from the oven and place on a wire rack to cool for at least 3 hours.
