Measure dimensions of six 1 1/4- to 1 1/2-cup casseroles or custard cups. On lightly floured surface roll each sheet of pastry into a 16 x 12-inch rectangle. Cut pastry into 6 pieces, each piece should measure 1 inch larger than the dimensions of the casseroles. Stack pastry pieces on plate, layering wax paper between each piece. Cover with plastic wrap. Refrigerate.
