How to Put in a Zipper

This is great, thank you! As a novice seamstress (I had no idea the male equivalent was "seamster," but I find that absolutely hilarious - sounds like "teamster"), I appreciate pictures!

Also - did you finish this? I wonder if you could sew in a dart to hide that run?

 

Thanks for the helpful tutorial! And "butt ruffle fin" will live in my head rent free
