A method of forming sheet metal skins of the inner fixed structure of a blocker door thrust reverser assembly having convex and concave curvatures. The method includes plastically stretching a sheet of metal about a mandrel having a chordwise central first axis to form a substantially convex shape. The method further includes the addition of features after the substantially convex shape is formed to facilitate plastically stretching a portion or portions of the substantially convex shape into a substantially concave shape about an axis that is substantially parallel to the chordwise central first axis.
