Preparation and Safety Guidelines

Tools Needed
  • Stretchy velvet fabric
  • Centimeter ruler
  • Pattern paper
  • Pins
  • Sewing machine
  • Bias tape (optional)
  • Fabric scissors
  • Gum/C tape
Safety Guidelines
  • Use sharp fabric shears for clean cuts to prevent fraying and ensure accurate draping. Dull shears can cause uneven cuts and damage the fabric.
  • Pre-wash your fabric before starting the project to avoid shrinkage after the top is completed. This is especially important for natural fibers.
  • Always test your chosen method on a scrap piece of fabric first to get a feel for the technique and ensure you're comfortable with the process before cutting into your main fabric.

Step-by-Step Instructions

  1. Pattern Drafting

    • Start with the basic body measurements (starting line, shoulder to B line, shoulder to waistline, neck width). Remember to account for fabric stretch.
    • Mark the neck width (3 inches for stretchy fabric) and depth (3 inches). Join the front neckline points using your C-curve ruler.
    • Mark the back neckline depth (1 inch) and width (3 inches).
    • Place half your shoulder measurement on the starting line. Go down by an inch and connect to the neck width to form the shoulder line.

    Pattern Drafting
    • Calculate and mark armhole height (your bust circumference / 6 + 1.5 inches). Place it down from the shoulder line and connect to create the armhole.
    • Mark half of the armhole height, go in by half an inch, and connect to the shoulder line. Create the armhole curve using your curve ruler.
    • Mark a quarter of your waist measurement plus 1 inch on the waistline and connect to the armhole.
    • Place half your nipple-to-nipple measurement on the bust line and waistline, then connect these points. Add half an inch on each side and connect to form the bust dart.

  2. Pattern Transfer and Cutting

    • Transfer the pattern to the other side of the paper, or cut it out first. Add seam allowance (0.5 inch for shoulder, 0.5-1 inch for sides/hem).
    • Cut out the back pattern, then transfer it to another fresh piece of paper for the back pattern piece.

  3. Front Pattern Modification (Slash and Spread)

    • For the front pattern, open it up from the shoulder and mark three points to connect to the bust line. Slash and spread the shoulder line from these points to the bust line, creating pleats.
    • Cut open each slash, spread, and secure the pleats using gum/C tape.
    • Cut out the armhole and neckline of the front pattern.

  5. Back Pattern Adjustment

Tips

  • Consider fabric stretch when determining neck and depth measurements.
  • Ensure the stretch direction of the fabric is considered when cutting out the pattern pieces.
  • Carefully pin and adjust pleats before stitching.

Common Mistakes to Avoid

1. Uneven Drape/Pleats

Reason: Inconsistent cutting or pulling of fabric during the draping/pleating process.
Solution: Carefully measure and mark fabric sections before cutting and maintain even tension while pleating/draping.

2. Incorrect Shoulder Seam Placement

Reason: Not accurately determining and marking the shoulder seamline before cutting and sewing.
Solution: Accurately measure and mark the shoulder seamline on the draped fabric before cutting and ensure proper alignment during sewing.

FAQs

What type of fabric works best for this project?
Lightweight to medium-weight fabrics that drape well are ideal. Think rayon, silk, crepe, or even a soft cotton. Avoid stiff fabrics like denim or canvas, as they won't drape properly.
