The facings of a garment are very important to professionally finish off a collar and armholes if it is going to be sleeveless or no collar at all.
To make these facings you do not need the base pattern but the pattern you have already modified. If you have changed the collar or have already removed the sleeves
The facings are pieces of fabric to finish off the neck and armholes and make the finish more polished and professional. These pieces are also used to finish off the seams so that they do not fray and show.
These pieces are interwoven so that they are glued together and the pieces are more assembled. I use a very thin interlining so that it doesn’t get too stiff and can be molded to my body. Many times I don’t weave it, especially if they are very fine fabrics.
How to make the facings
Let’s take our pattern and a sheet of tracing paper to trace the shape of the armholes and the neck separately.
The views are usually 2 cm wide (not counting the sewing margins) to ensure that nothing will be seen.
The width of the facings is made towards the inside of the pattern. For the armholes, we take 2cm from the shoulders and 2cm from the side of the chest. And we follow the shape of the armhole without losing those 2cm of width all around. Then we add the sewing margins.
For the ones on the neck, it’s the same. Only we take 2cm from the center front and back and another 2cm from the shoulder.
When you already have them cut with the same fabric of the shirt or dress, we can weave them if we want. But don’t glue it yet. Sew it to the garment, fold the edges of the facings inwards so that they are glued too, and they are finished off. Another option is to finish it off with a blind stitch.
