Preparation and Safety Guidelines

Tools Needed
  • Pattern (knit bodice block or t-shirt pattern)

  • Ruler
  • Pencil/Sharpie
  • Measuring Tape
  • Heat Erasable Pen/Chalk/Pins
  • Fabric
  • Ribbing (optional)

Safety Guidelines
  • Use sharp sewing shears or a rotary cutter for clean fabric cuts to prevent fraying and ensure accurate neckline shaping.
  • Always test your stitch settings on a scrap fabric of the same knit type before sewing on your project to avoid damaging the garment or causing unwanted puckering.
  • Handle your needles and pins carefully to avoid accidental pricks or injuries. Use a pincushion to keep them organized and readily accessible.

  7. Prepare the Neckband

    • Cut a strip of ribbing or self-fabric based on your measured neckline length and desired width (2 inches including seam allowance).
    • Fold the neckband in half (wrong sides together). Position it on the neckline, overlapping by the seam allowance. Form a V-shape that matches the garment’s V-neckline, marking and trimming the ends to match the angle. Shorten the neckband slightly (1-2 inches) to allow for a neat fit.

Tips

  • Use a pencil for cleaner lines when creating your template.
  • Use a practice fabric first, especially if you're new to V-necklines.

  • Adding seam allowances and hem allowances is crucial when cutting fabric.
  • Basting the neckband is highly recommended for a neat result.

Common Mistakes to Avoid

1. Uneven V-Neckline

Reason: Inaccurate measuring or cutting of the neckline, leading to one side being higher or lower than the other.
Solution: Carefully re-measure and adjust the neckline before sewing, ensuring both sides are perfectly symmetrical.

2. Stretchy Neckline

Reason: Using a knit fabric that stretches too much without stabilizing the neckline with interfacing or a firm stitch.
Solution: Apply lightweight interfacing to the neckline facing before sewing to prevent stretching and maintain the V-shape.

3. Gaping V-Neckline

Reason: Insufficient ease or improper fitting of the neckline, leading to a large gap at the center point of the V.
Solution: Reduce the neckline opening slightly, or add a small amount of gathering to the neckline facing to close the gap.

FAQs

How do I prevent stretching or distortion around the V-neckline while sewing?
Use a lightweight, stable interfacing on the neckline facing before sewing. Stitch slowly and carefully, using a small stitch length. Consider using a stretch stitch on your machine if working with a knit fabric that has significant stretch.
What type of neckline finish is best for a knit V-neck?
A narrow, bias-bound neckline finish or a self-bound neckline (using strips cut from the same fabric) are ideal for knits. They provide a clean finish and accommodate the stretch of the fabric.
My V-neckline is too wide/narrow after sewing. How can I adjust it?
Before sewing the final neckline seam, carefully baste the facing to the neckline. Try it on to check the fit. If it's too wide, you can slightly reduce the seam allowance. If it's too narrow, you may need to carefully unpick and re-sew, or use a slightly larger seam allowance for the next attempt.
