Heyhey,
so my jacket and shorts are almost finished, sorry, I am a little slow at the moment, I am alraedy planning some stuff with the move, and somehow I dont have a productive phase right now;). Anyhow here are the steps for the zipper in the shorts:
use overedging for the centre front of both front parts and the sew the crotch seam until the beginning of the opening for the zipper
fold the right side inside a few mm next to the centre front line, and pin the open zipper under it and sew close to the edge
then pin the zipper-opening closed
close the zipper and pin it to the seam allowance on the left side
only to the seam allowance, the sew
next sew from the right a line, starting at the beginning of the opening in a 45° angle, and at the right distance parallel to the fold
looks like this from the side by now
next you need on part with the length of the opening and as wide as you stitching is, cut in fold, fold together and serge the open side
place it on the lower side of the zipper and sew it to the seam allowance
also sew it with a few stitches to the seam allowance at the end
I hope this was helpful for you, if you have any questions please let me know. You can still enter at the fabric giveaway.
keep sewing and smiling
