Does anyone know of a good tutorial on how to insert a fly zipper on a pair of pants? There seems to be a bunch for skirts but I haven't come across one for pants. I have sewn my first pair of jeans for my 3 year son and after a few attempts I still kept getting a weird bunching-puckering right at the crotch-meets-zipper area. Any suggestions on how to avoid this?
Yes! Sandra Betzina has a great fly zipper tutorial here - http://www.threadsmagazine.com/item/3831/video-an-easy-flat-fly-fro...
That was really helpful and made much more sense than what the pattern suggested.
