    How to Master Curved Seams on a Sewing Machine — Inward & Outward Curves Explained

    Let’s be honest — curved seams can be the sewing equivalent of parallel parking. Awkward at first, but incredibly satisfying when done right. If you’re into embroidery designs or machine sewing, you’ve probably faced a few wobbly curves. We've been there too. In this guide, we share our go-to techniques to help you nail both inward and outward curves with confidence and precision.

    Inward Curves

    Gently curved inward seam in progress. Patience is your best friend here!

    1. Cut and Sew:
      • Align two fabric pieces with right sides together along the inward curve.
      • Use a straight stitch and a 5⁄8" (1.5 cm) seam allowance. Guide slowly — don’t rush the curve!
    2. Trim and Grade:
      • Trim the seam allowance down to 1⁄4" (.6 cm).
      • Grade the seam by trimming one layer closer to the stitching, then notch carefully to ease the curve.
    3. Press:
      • Press the seam open from the inside, then turn right-side out and press flat for a neat finish.

    Outward Curves

    Sewing an outward curved seam

    Outward seams tend to puff — but don’t worry, we’ve got just the trick.

    1. Cut and Sew:
      • Start with fabric right sides together along a gentle curve.
      • Straight stitch while subtly guiding the fabric — the curve will want to resist, but you’re in control.
    2. Pivot at Tight Turns:
      • For tight curves, stop, lift the presser foot, pivot slightly, then resume. Like steering around a roundabout.
    3. Maintain Flow:
      • Keep the stitch smooth to avoid pointy corners. Think: curve = no elbows.
    4. Trim and Notch:
      • Notch evenly across both layers to reduce bulk and maintain shape.
    5. Final Press:
      • Turn right side out and give it a good steam press for that pro finish.

    Tips from Experience

    "I once sewed a sleeve inside-out for the third time in a row. Took a deep breath, grabbed a snack, and started again. Moral of the story? Curves demand patience — and snacks." 🍪

    • Use contrasting thread on test fabric to better see how your machine handles curves.
    • Use small scissors or duckbill appliqué scissors for cleaner trimming.
    • Practice on scrap before going full couture.
