Each facing follows its own neckline
Front and back lengths remain separate so the pieces can follow different curve depth and shape.
Generate front and back neckline facings with seam allowance, center-fold guides, shoulder notches, and print-ready exports. Use the finished neckline from a bodice or dress, or enter front and back neckline lengths manually.
Generated example
The example uses 12.2 cm for the front half-neckline, 8.8 cm for the back, and a 5 cm facing depth to build two coordinated facing pieces.
Front and back lengths remain separate so the pieces can follow different curve depth and shape.
The two half-neckline values are doubled across the folds to represent the full finished neckline.
Source links from bodice and dress generators can transfer both the measured lengths and available curve-shape data into the facing tool.
Both facings use the same geometry in tiled A4 PDF, full-size PDF, and SVG.

Neck facing guide
The generator drafts separate front and back facing half-patterns on fold. The inner facing curves are fitted to the front and back neckline seam lengths, while the outer curves create a stable finishing width for clean sewing.
The export includes front and back facing pieces, inner neckline seam curves, outer facing curves, dashed seam allowance, center-fold lines, shoulder notches, labels, and a 5 × 5 cm test square.
Use the finished neckline seam lengths from the garment, not body neck circumference. When started from a basic bodice or dress, these values are filled from the generated geometry.
Facing width controls how deep the internal finish sits inside the garment. Seam allowance is added as a cutting guide around the facing pieces.
Compare the facing inner curves with the prepared neckline and test the shoulder join before cutting final fabric or interfacing.
Print at actual size or 100%, disable page scaling, and verify the 5 × 5 cm square before cutting.
Who, how, and when
This generator is maintained as application code: measurements are converted into vector geometry, related seams are measured numerically where the construction requires it, and the same geometry is used for preview, SVG, copyshop PDF, and tiled A4 PDF.
Generator content and output workflow reviewed 13 July 2026. A generated block remains a fitting starting point; verify measurements, print scale, fabric behaviour, and a test garment.
Common questions
Yes. A neck facing finishes the neckline on the inside of the garment, while a collar is a visible external piece attached to the neckline.
The generator can show the total length, but the draft uses separate front and back neckline lengths so each facing piece matches its garment section.
Yes. Basic bodice and dress previews pass the calculated front and back neckline lengths directly into this generator.
A standard 4–6 cm facing is suitable for many woven garments. Use a narrower facing for lightweight styles and a deeper facing when the neckline needs more stability.
Print at actual size or 100%, disable fit-to-page scaling, and check the 5 × 5 cm test square before cutting fabric.
Workflow
Start from the finished front and back neckline lengths, either manually or from a generated bodice or dress.
Select standard, narrow, or deeper facing width and seam allowance.
