Preparation and Safety Guidelines

Tools Needed
  • Ruler
  • Sewing machine
  • Chalk
  • Woven knit stay tape
  • Iron
  • Pins
  • Taylor's Ham (optional)
  • Silk kimono thread (optional)
Safety Guidelines
  • Always use sharp scissors or rotary cutter for clean cuts, especially on curved hems. Dull blades can cause fraying and inaccurate cutting.
  • Pinning is crucial! Securely pin the hem allowance to prevent shifting and ensure an even curve during stitching. Use plenty of pins, especially in areas with a tight curve.
  • Test your stitch length on scrap fabric first. A shorter stitch length is recommended for curved seams to prevent stretching and distortion. Too long a stitch might cause the hem to pucker.

Step-by-Step Instructions

  1. Marking and Stitching the Hem Allowance

    • Mark a half-inch hem allowance along the curved edge of the flutter sleeve using a ruler and chalk.
    • Stitch along the chalk line using a short stitch length to create a guide for turning the hem.

  2. Applying Stay Tape

    • Apply woven knit stay tape to the raw edge of the hem, using an iron to fuse it in place. This adds stability and helps the curve hold its shape.

Tips

  • To prevent bias edges from stretching, use woven stay tape immediately after cutting pattern pieces. Steam and press the fabric back to its original size if stretching occurs.
  • Pinning the hem to the ironing board prevents chasing fabric with a hot iron.
  • Use glass-head pins that can withstand heat while pressing.
  • When attaching flutter sleeves to the armhole, adjust the placement of the sleeve cap to account for differences in the front and back armhole lengths. Use the feed dogs on your sewing machine to ease the sleeve cap into the armhole, pulling the sleeve cap fabric slightly faster than the armhole fabric.
  • Sew slowly to avoid puckers when attaching the sleeve cap to the armhole.

Common Mistakes to Avoid

1. Uneven Hem Curve

Reason: Inaccurate measuring or inconsistent pulling of fabric during stitching leads to a lopsided or bumpy hemline.
Solution: Carefully measure and mark your curve before stitching, and maintain consistent tension on the fabric while sewing.

2. Puckering or Gathering at the Curve

Reason: Too much fabric is gathered at the curve due to insufficient ease allowance or stretching of the fabric during sewing.
Solution: Add more ease to your pattern or use a smaller stitch length and gently stretch the fabric to ensure a smooth curve.

FAQs

How do I ensure the curve of my Flutter sleeve hem is smooth and even?
Use a lightweight, flexible interfacing along the curve before sewing. This will help prevent stretching and give you a cleaner finish. Also, carefully clip into the seam allowance curves after sewing to ease the fabric and prevent puckering.
What type of fabric works best for flutter sleeves?
Lightweight to medium-weight fabrics like cotton voile, chiffon, rayon, or silk work beautifully. Heavier fabrics can make the flutter less dramatic. Avoid stiff fabrics that won't drape well.
My flutter sleeve hem is uneven. How can I fix it?
Before you sew the hem, carefully pin and baste the curve to ensure even distribution of fabric. If it's already sewn, carefully unpick the stitching, re-pin, and re-sew. If the unevenness is minor, you can gently steam the hem to help it settle.
