Whether you’re a beginner or have experience, machine hemming saves time and helps you achieve top-quality results.
Essential Tools and Materials
Before you start hemming, gather these supplies:
- Sewing machine (with the right needle for your fabric)
- Matching thread
- Scissors or rotary cutter
- Fabric marker or chalk
- Measuring tape or ruler
- Pins or fabric clips
- Iron and ironing board
- Seam ripper (for fixes and adjustments)
- Ruler or hem gauge
Having the right materials ensures a smoother process and a cleaner finish.
Step-by-Step Guide: How to Hem a Dress With a Sewing Machine
Hemming a dress can be broken down into manageable steps. Follow this simple process for great results every time.
1. Try On and Mark the Desired Length
- Put on the dress with the shoes you’ll wear most often.
- Stand in front of a mirror.
- Use a friend or pin marker to help you mark the ideal hem length using fabric chalk or removable marker.
- Double-check on both sides and the back to ensure evenness.
2. Measure, Mark, and Trim (Optional)
- Lay the dress flat and measure upwards from the bottom edge to your marked hemline.
- Use a ruler or tape to draw a straight line around the dress.
- If excess fabric needs to be removed, add your hem allowance (commonly 1 to 2 inches) below your hemline mark, then cut off the extra fabric.
3. Finish the Raw Edge
Finishing the raw edge allows for a neater hem and prevents fraying. Pick a method suitable for your fabric:
- Zigzag Stitch: Run a zigzag stitch along the edge to prevent fraying.
- Serger (Overlock): Use a serger if available for the cleanest finish.
- Fold Once: For thicker fabrics, a single fold may suffice before final hemming.
4. Iron the Hem Fold
- Fold the raw edge up towards the wrong side (inside) of the dress by your chosen hem allowance, typically 1 inch.
- Press sharply with an iron for a crisp edge. This step makes sewing easier and results more professional.
5. Pin or Clip the Hem in Place
- Use pins or fabric clips to secure the hem all the way around.
- Ensure the hem is even by checking with a ruler or hem gauge.
6. Sew the Hem
- Set your sewing machine to a straight stitch (preferred for most hems).
- Start at a side seam to keep the join less noticeable.
- Sew close to the folded edge (about 1/8 inch away) around the whole hem.
- Backstitch at the start and end for reinforcement.
Optional: Stitch Variations
- Blind Hem Stitch: For an almost invisible hem, use a blind hem foot or stitch setting.
- Decorative Stitch: Some fabrics look great with a visible, decorative hem.
7. Remove Pins and Press Again
- Take out all pins or clips.
- Press the hem one last time for sharpness and a polished finish.
Types of Machine Hems for Different Dress Fabrics
Different dresses benefit from unique hemming techniques. Consider:
- Folded Hem: The standard double-fold hem is sturdy and works for cotton, denim, and many casual fabrics.
- Rolled Hem: Perfect for lightweight fabrics like silk, chiffon, or organza. A rolled hem foot can help achieve this delicate finish.
- Blind Hem: Ideal for dressy or formal fabrics where you want the hem stitches hidden from view.
- Faced Hem: For very curved or thick hems, sew on a facing (a separate strip of fabric) to stabilize the hem before folding and stitching.
Matching your hemming technique to your fabric not only looks better but helps the dress hang and move beautifully.
Troubleshooting & Overcoming Common Hemming Challenges
Even the most experienced sewists encounter hiccups. Here’s how to tackle some common issues:
- Wavy or Stretched Hems: For stretchy or slippery fabrics, use a walking foot, stabilize with tissue paper, or lower machine tension.
- Unmatched Thread: Always test several thread shades on a scrap to get the closest color match.
- Crooked Hemlines: Use a hem gauge, measure around the skirt multiple times, and press before sewing for accuracy.
- Fabric Gathering: If the fabric bunches under the presser foot, gently guide it and avoid pulling while sewing.
Taking your time and troubleshooting as you go prevents frustration and ensures the best result.
Pro Tips for Flawless Machine Hems
To amp up your hemming game, keep these expert suggestions in mind:
- Test on Scrap Fabric: Always sew a sample on leftover fabric before working on your dress. Adjust stitch length and tension as needed.
- Choose the Right Needle: Lightweight fabrics need fine needles (size 70/10 or smaller), while heavier fabrics require larger, sharper needles.
- Invest in a Blind Hem Foot: This presser foot helps make neat, hidden hems, especially for dressy garments.
- Press Throughout: Ironing at every stage—before, during, and after sewing—gives a crisp, tailored look.
- Go Slow on Curves: Gently ease curved hems and go slowly to prevent puckering.
Good prep and the right technique make all the difference between a homemade and a handmade finish.
Practical Benefits of Hemming Your Own Dresses
- Customization: Adjust dresses for different shoes or personal style.
- Cost-Effective: Save on alteration fees.
- Sustainability: Extend the life of favorite garments instead of replacing them.
- Skill Building: Improve your confidence and ability with each project.
Personalizing your wardrobe is both practical and rewarding. Hemming is a foundational skill for any sewing enthusiast.

Frequently Asked Questions (FAQs)
1. How much hem allowance should I leave when hemming a dress?
A standard hem allowance is 1 to 2 inches (2.5 to 5 cm), but this can vary based on the style of the dress and fabric thickness. Lighter fabrics often get a narrower hem, while heavier fabrics may need a deeper allowance for weight and stability.
2. Can I hem a dress made from stretchy or knit fabric with a regular sewing machine?
Yes, you can hem knit or stretchy fabrics on a regular sewing machine. Use a stretch needle and a zigzag or stretch stitch, or a twin needle for more elasticity. This allows the hem to move and stretch with the fabric, preventing broken threads.
3. How do I keep my hem stitch lines straight?
Go slowly and use the sewing machine’s guidelines on the needle plate to keep your distance from the hem edge even. Press the hem sharply and use lots of pins or clips to guide you as you sew.
4. What should I do if my hem turns out wavy or puckered?
Wavy hems often result from too much tension, using the wrong needle, or stretching the fabric as you sew. Try using a walking foot, stabilizing with tissue paper under the fabric, or adjusting your stitch length and tension. Testing on a scrap first can help avoid this issue.
5. Is a blind hem worth learning for hemming dresses?
Absolutely! A blind hem is nearly invisible and gives a professional finish, making it ideal for dress pants, skirts, and more formal dresses. Once you’ve mastered the technique, you’ll find it’s a valuable skill for upgrading the look of your sewn garments.
With patience, practice, and the tips above, hemming a dress with your sewing machine becomes a straightforward and satisfying project. Happy sewing!
