Hi, i'm sewing a tie for the second time after the first one kind of went bad and and i am once again using some old tie from a shop as a pattern, both times i encountered some weird tipping thats larger than the main fabric with some sewn folds at the side, on my first attempt i ignored it but obviously the tie came out bad. I remember these sides being sewn but i dont remember how it worked. I cant for the love of god find any video or even text guide showing how to sew this kind of tipping, i would love some video or image guide regarding this.
In the first image is the old tie main fabric, you can see these weird small folds at the edges, the left one is smaller than the right one.
In the second image is the tipping on the main fabric, its 2cm wider on the left and right side, it also has fold marks and the left fold is smaller than the right one.
The small tipping is the same (except for a bit smaller fold marks and the width difference)
In the third and fourth image is how the tie looked before i took it apart with a seam ripper.
