Video: An Easy, Flat Fly-Front Zipper - Threads (aka THE BEST FLY FRONT ZIPPER TUTORIAL IN THE WORLD)
Ignore the pattern instructions, says Sandra Betzina, and use this simplified version for “ready-to-wear” results.
For years and years of sewing I was REALLY TERRIBLE at sewing in zippers in general and fly-front zippers in particular. I’d go to some serious lengths to avoid having to make them; once I even put in a topstitched-in zipper on the side seam of my pants and a fake topstitched fly in the front.
Then I saw this video.
This is literally the first method of sewing a fly-front zipper that ever made serious sense to me, and now the other methods and pattern instructions are a lot less frightening once I really “got it”. If you’re having trouble sewing in the fly of a pair of pants you’re making, try this! I hope it helps at least one person who’s struggling or dealing with con crunch.
