Preparation and Safety Guidelines

Tools Needed
  • sewing machine
  • zipper
  • fabric
  • scissors
  • pins
  • measuring tape
  • iron
  • zipper foot (optional)

Safety Guidelines
  • Always use sharp sewing machine needles and sharp scissors to prevent fabric from stretching or fraying. Dull tools can lead to uneven seams and frustration.

Tips

  • Use a zipper foot for easier zipper application.
  • When sewing the zipper onto the zipper facing, ensure you only sew the facing, not the skirt panel. Fold the skirt panel out of the way.
  • Use a 5/8 inch seam allowance for the back seam to avoid fitting issues.
  • Be careful when hammering the button onto the waistband to avoid hitting your fingers.

Common Mistakes to Avoid

1. Uneven Zipper Insertion

Reason: The zipper teeth aren't aligned perfectly with the skirt's seam allowance, resulting in a crooked or gapped zipper.
Solution: Carefully baste the zipper in place before sewing to ensure even alignment and prevent gaps.

2. Inconsistent Seam Allowance

Reason: Varying seam allowances around the zipper opening cause the fabric to pucker or pull unevenly, affecting the zipper's smooth function and the skirt's fit.
Solution: Use a consistent seam allowance throughout the construction process, marking it with tailor's chalk or a marking pen for precision.

FAQs

What type of zipper is best for a pencil skirt?
A separating zipper (the kind that opens and closes completely) is ideal for a pencil skirt as it allows for easy on and off. Choose a zipper that matches your fabric in color and weight.
How important is accurate measuring for a pencil skirt?
Extremely important! A pencil skirt's fit relies heavily on precise measurements. Take your time and double-check your measurements before cutting your fabric. Consider using a flexible measuring tape and having someone help you with back measurements.
What if my zipper is crooked after I sew it in?
Don't panic! If your zipper is slightly crooked, carefully unpick the stitches and re-sew, paying close attention to aligning the zipper tape with the skirt seams. Using a zipper foot on your sewing machine can significantly help with straight stitching.
