How to hem a double-fold curve | Clean & professional finish
A double-fold hem encloses all raw edges for a durable, clean finish — and on a curved edge, a basting stitch is the key to keeping everything smooth and pucker-free. This technique is ideal for curved hems on skirts, dresses, and any garment where you want a neat result that lasts.
Materials needed
- Fabric with a curved edge
- Matching thread
- Sewing machine
- Iron
- Pins or clips
Step-by-step instructions
-
Sew a basting stitch
Sew a long basting stitch approximately 1 cm (⅜″) from the raw edge of the fabric. This stitch acts as a guide for the first fold and helps ease the curve accurately without distortion.
-
Fold along the basting line and press
Fold the fabric along the basting stitch line, using it as your guide, and press carefully with an iron to shape the curve. The iron does the work of easing the fabric into the curved shape — take your time here.
-
Remove the basting stitch
Once the fold has been pressed and holds its shape, gently remove the basting stitches. Press again lightly to keep the fold crisp and smooth before making the second fold.
-
Fold the hem a second time
Fold the edge once more, using the first fold as your guide, to create a clean double-fold that fully encloses the raw edge. Press well all the way around to set the shape firmly before pinning.
-
Pin the hem
Pin or clip the hem evenly along the curve to hold it securely in place. Space the pins closely on tighter curves to prevent the fold from shifting while you sew.
-
Sew the hem
Using a short stitch length, sew close to the inner folded edge, following the curve smoothly and evenly. Sew slowly around any tighter sections for a consistent, professional finish.
Pro tip
This method works best on light- to medium-weight fabrics. Accurate pressing is the single most important factor in a smooth curved hem — take your time at every pressing step and use the tip of the iron to ease the curve rather than flattening it with the full plate.
