I remember when I was younger watching my mom make a pumpkin pie for a church potluck. I watched as she painstakingly took a long strip of aluminum foil and tacked it around the pie with toothpicks. Of course, whenever I have tried this it always fell off. As I watched the crust of my quiche getting too toasty I was debating on whether I should try it again when I got this idea. It worked perfectly and only took me about a minute. Really.
I pulled off a sheet of aluminum foil and put one of my dinner plates on it upside-down. My plates are 11 inches in diameter and I'm sure that is a pretty standard size. My pie plates are 9 inches. You can go around it with an ink pen to make things easier but you don't have to. The ink doesn't matter: it is the impression it makes. Then you hold the plate down while you pull the foil up and tear it off around the plate edge.
Then I just used my fingers to bend the edge down about half an inch from the edge.
