In our last pattern cutting lesson we looked at inserting a fly zip. I found this really interesting as it is the first zip that I have tried which uses separate pieces as well as the zip and main garment pieces.
Here is how I did it:
Sew the crotch area 1.5cm seam allowance up to the fly notch.
Tack the zip to the facing and fold up the bottom of the tape.
Secure the zip by sewing down the middle of the zip tape and curve the line under the stopper.
Pin the Placket/Zip Shield to the back of the zip making sure it covers all the zip.
Sew a line of stitching as close to the edge of the fabric as possible.
To add some extra finishing touches to the zip secure all the layers together using a short line of stitching; making sure you go over it few times to secure it.
Why don't you give it a try?
