Hello, today I bring you a shirt that has a heart on the back. The sizes range from 36 to 56, with their colors to differentiate them.
As you can see, in this case we will trace a "Dior" clip, also this mold is designed to reach the waist, not the hips. If you want it to reach the hip, you must lengthen another 20.0 cm and close the clamp.
The same happens in the back mold, the length is up to the waist, to lengthen it just add about 20.0 cm. If they do, the 7.0 cm will lengthen until the end of the garment. If they don't, it will look like the drawing.
The measurements, in pen, both on the front and on the back, do not vary according to size.
This is how they should put the mold on the fabric. Something that I would like to clarify is that, the part of the front mold that says X2, means that it has to be cut twice, since then they will be sewn on both sides.
In this case, the paper mold has a square neck, but I drew a round one, since it is easier to sew. Don't forget to leave 1.0 cm for the seam allowance, this applies to the entire mold.
Once we have everything cut, we begin to sew. The first thing we have to do is secure the clips and sew them, as seen in the image. This is all just the front part.
Then we sew a front shoulder, with a back one, and make the neck. As always, I do it by folding the fabric, then I sew it and finally I close the other shoulder.
This is how the neck looks if they do it like I do. This does not mean that you have to do it if or if so, you can do it the way you like best.
As this shirt has no sleeves to add to them, what I did was the same as the neck, fold the fabric and then sew it. As seen in the image.
When we have the "sleeves" finished, we sew the sides and finally we make the hem. This is how we finish the shirt.
In this case, the fabric does not lose the threads, so do not secure the heart. In the event that the fabric you choose should lose the threads, what you have to do is secure it, either by overlocking the entire edge or by sewing a tape to cover it.

And this is how the heart looks on the back. Another thing they can also do is sew a tulle inside the heart or any other fabric.
