Pie receipes often instruct you to place foil around the edges of the crust to keep it from darkening too quickly - and you find yourself fumbling with long, straight strips.  Next time try this more sensible one-sheet trick.

Step 1:  Fold a 12" square piece of foil in half, forming a rectangle.

Step 2:  Fold the foil in half again, forming a square.

Step 3:  With scissors, cut out a quarter-circle shape, starting about 3 to 4 inches from the folded corner of the square; discard.

Step 4:  Unfold the foil.  Check that the opening is the correct size by holding it over the pie.  The foil should cover just the rim of the crust.  (If the hole is too small, refold the foil and cut out a larger circle.)  Tuck the edge of the foil under the pie plate and continue baking the pie for the time instructed.
