I’ll admit that I avoid sewing projects that require a zipper fly.  It’s hard to look at a completed fly and intuit the construction process, and the instructions in a pattern look complicated.  Colette Patterns shares a tutorial on their blog, The Coletterie, showing how to sew one in.  They give step-by-step photos so you can see exactly how it’s done.  Get the tutorial.
