Offset center shuttlecock

I use this method of constructing a shuttlecock when it is necessary to achieve different intensities of undulation.

This is my first master class, but I will try to explain everything and demonstrate it in an accessible way. And I want to show how I construct shuttlecocks in those cases when it is necessary to achieve different undulations.
To get started, I chose the model I want to recreate.
As a basis, I will take the pullover model, because I tried it on my previous product. As a fabric - knitwear with a high content of elastane. I chose this fabric in order to create a fitted silhouette with a minimum of seams. We have patterns of shelves and backs, in which it is necessary to make the appropriate changes. We connect the point, A (the point lying on the shoulder line) and the point B (the point lying under the armhole with a smooth line). Cut off.

Back


Now we need to duplicate the line of the top cut of the top, we get a blank for the shuttlecock. You can create two separate blanks for the shelf and backrest if the curves of these parts are very different, as in this blouse. But in this case, you can use one blank. Next, we determine the length of the shuttle (segments AC and BD). Judging by the picture, the length of the shuttlecock along the shoulder line is slightly larger than under the armhole. Accordingly, we take AC = 27cm, BD = 24. And so we get

Now you need to cut the workpiece for further disclosure.

We cut out the details from the fabric.
Shelf back


Adhesive trimmed with glue

We open the shuttle blank so that the curvature of the upper cut is in the place where the expected waviness should be greater. Since the back does not have significant bulges, the wavy of the shuttlecock is less than on the shelf. Accordingly, we cut out the shuttlecocks of the shelf and back.
Shelf


Back


We grind the details of the shelf and backrest on the right side seam, the shuttle details on the BD segments. We lay out the stitched parts of the canopy and the back face up. We impose the details of the shuttlecock with the wrong side on the front side of the shelf and back. We chop off as follows

We lay the fixing line. Further, everything is according to the standard scheme. We grind off the remaining side seam, then the shoulder seam, capturing sections of shuttlecocks. The upper section of the top is processed with a fine cutter. We bend the bottom and lay the line. That's all!!!
The result should be something like this

P. S. Regarding the poncho blouse

then the shuttle takes the form


I hope it was useful with my advice!
