A fly front closure to pants not only gives it a more professional finish, but it is more functional then a side zipper. I will be showing my go-to method for sewing a fly front in an upcoming post, but I would first like to start out by deconstructing the fly front closure so we are all talking about the same thing. If you have any questions or comments about sewing a fly front hit up the comments form and I will try to address them in the upcoming tutorial.
