Prepare a 9-inch pie plate by rubbing inside, bottom, and sides with 1 teaspoon of the margarine; set aside.

Crush vanilla wafers to make very fine crumbs (1 1/4 cups). Place crumbs in a large bowl; combine vanilla and melted margarine and drizzle all over crumbs. Mix thoroughly with a blending fork to make sure all is well blended.

Remove about 2 tablespoons of crumb mixture and set aside to use if desired as a garnish on top of pie. With back of a large spoon, press remaining crumbs evenly all over bottom and sides of prepared pie pan. Chill in refrigerator 2 hours or longer before filling.
