Sewing Pants Zipper : An Easy way to zip the fly

A Pant Fly refers to the short opening over the crotch line in pants. A zippered fly has a zipper fastener securing the opening of the fly; this opening has to be sewn in such a way that the zipper is concealed and fixed to the inside.

I read countless tutorials to learn it but somehow I couldnot make head or tail of it.Now at last I have found the easy way to do it. 

Count on you to find the easiest way, lazy goose“, said the fly to the spider!

Stitch in place; you may have to hand baste in place or pin so that everything will stay in place while you sew it.

You will also have to use a zipper pressure foot so that you can stitch really close to the zipper tooth

As a final touch you can top stitch  over the left side of the pant ( when you wear it) along the zipper in a  curved line over the facing, fixing everything in place. Look at the fly in the jeans for an idea .
