A method comprising: providing a main body piece formed of an elastic fabric material, the main body piece having a first portion having a first end and a second portion having a second end opposite the first end and two side ends extending between the first and second ends, the main body piece having a hole through the first portion; placing a housing in contact with the main body piece, the housing being made from a polymer material having a rigidity greater than the elastic fabric material, the housing defining a cavity and having an access opening permitting access to the cavity to receive an electronic module ; folding the main body piece by moving the first and second ends together and connecting the first and second ends together to define a folded main body piece, such that the first portion confronts the second portion, defining a fold line between the first and second portions, wherein the housing is positioned between the first and second portions and a portion of the housing including the access opening is received in the hole through the first portion, such that the access opening is accessible; and bending the folded main body piece and connecting the side ends together to form a band having a tubular body defining a central passage extending in an axial direction, wherein the band is an armband or wristband configured to be worn on a user's arm such that a portion of the user's arm is received in the central passage, and wherein the housing defines a pocket that is configured to removably receive the electronic module through the access opening such that the electronic module is retained in the band. providing a main body piece formed of an elastic fabric material, the main body piece having a first portion having a first end and a second portion having a second end opposite the first end and two side ends extending between the first and second ends, the main body piece having a hole through the first portion; placing a housing in contact with the main body piece, the housing being made from a polymer material having a rigidity greater than the elastic fabric material, the housing defining a cavity and having an access opening permitting access to the cavity to receive an electronic module ; folding the main body piece by moving the first and second ends together and connecting the first and second ends together to define a folded main body piece, such that the first portion confronts the second portion, defining a fold line between the first and second portions, wherein the housing is positioned between the first and second portions and a portion of the housing including the access opening is received in the hole through the first portion, such that the access opening is accessible; and bending the folded main body piece and connecting the side ends together to form a band having a tubular body defining a central passage extending in an axial direction, wherein the band is an armband or wristband configured to be worn on a user's arm such that a portion of the user's arm is received in the central passage, and wherein the housing defines a pocket that is configured to removably receive the electronic module through the access opening such that the electronic module is retained in the band. <EOS>
