Two Types Of Garment Front Opening Facings
A front opening facing is used to clean finish the garment opening and neckline edges simultaneously. Conventionally the front neck facing is built into the garment opening facing and the facing that cover the back neckline is cut separately. While the back facing is almost always cut separately and stitch to the shoulder seams and garment neckline, that is not always the case with the front facing layer. Here are two types of front opening facings you should know:
An extension front opening facing is built into the garment patterns and simply folded down the garment's center front to expose the clean finished edges. This facing style is very easy to distinguish- if you take a look at the garment's open edge, there should be a simple fold instead of a seam.
The front garment portions have a built in facing extension. The line that separate the facing portion form the garment is the fold line and often, also the center front line. This line should be transferred to the wrong side of the garment to provide a folding guide during the construction process. When folded the facing's neckline edge should perfectly match that of the garment portion.
A separate front opening facing is cut and stitched separately and not built into the garment's patterns. In your pattern set, these facing layers will have separate pattern pieces. If you take a look at the finished garment's opening edges, you should see a clearly defined seamline running along the edge.
When sewing a separate front opening facing, each front facing is cut separately then stitched to each corresponding front garment opening edge to enclose its raw edges. The back facing piece, which is used to clean finish the garment's back neckline, connects to the front facing's shoulder seam edges to complete the entire neckline edge.
