A method of manufacturing a smoking article (10) comprises providing a mouthpiece (14) and an aerosol generating substrate (12) in axial alignment with the mouthpiece (14). The mouthpiece (14) includes one or more segments (16) and a substantially transparent wrapper (18) circumscribing at least a portion of the one or more segments (16). A sheet of paper material is provided and comprises a window in the paper material. The ratio of shrinkage of the substantially transparent wrapper (18) to shrinkage of the paper material at the time of manufacture of the smoking article is less than 3.5 when subjected to 15 percent relative humidity at 42 degrees Celsius for 3 hours. The sheet of paper material is wrapped around at least a portion of the transparent wrapper (18) so that an underlying mouthpiece segment can be viewed through the window and the substantially transparent wrapper (18).
