How to clip a curved seam allowance - Sewing Tutorial (Copy)
Hi there sewing friends !
Today, I’m excited to share a sewing technique that can add a truly professional touch to your garments—clipping curved seam allowances. If you’ve ventured into sewing pieces with curved seams, you’ve probably noticed that achieving a smooth, flat finish on areas like necklines, armholes, and pocket openings can be tricky. That’s where clipping comes in! This simple technique allows the seam allowance to spread and relax along the curve, giving your project that polished, store-bought look.
Why Clipping Seam Allowances is Important
When sewing a curved seam, the outer edge of the fabric has more volume than the inner edge. If left untrimmed, this excess fabric can cause puckering or bulkiness when you turn your project right-side out. Clipping the seam allowance allows the fabric to spread and lay flat, resulting in a clean, smooth curve.
Where to Use This Technique
Necklines: To ensure your collar lays flat against your neck without any puckering.
Armholes: For comfortable arm movement and a professional look.
Curved Hems: For skirts or dresses with a curved edge.
Pockets: To maintain the shape and function without added bulk.
Any Inner Curve: Wherever the fabric turns inward, and you want a flat, smooth finish.
Step-by-Step Guide to Clipping Curved Seam Allowances
Materials required
Fabric with a Curved Seam: Practice on a scrap piece or your current project.
Snips or Small Scissors: I recommend LDH snap snips for precision.
Iron and Ironing Board: A Birch mini iron is fantastic for small areas.
Pins: To hold the fabric in place if needed.
Step 1: Sew Your Curved Seam
Begin by sewing your curved seam with the appropriate seam allowance, typically 1 cm (3/8 inch). Use a consistent stitch length to ensure durability.
Step 2: Clip the Seam Allowance
Lay Your Fabric Flat: Place your project on the ironing board with the seam allowance facing up.
Start Clipping: Using your snips, make small cuts into the seam allowance perpendicular to the stitch line.
Important: Stop just before the stitch line—avoid cutting through it.
Space your clips about 2–2.5 cm (1 inch) apart. For tighter curves, make the clips closer together.
Accidentally Snipped the Stitch Line? Don't worry! If you accidentally cut through the stitch line, simply re-sew that section of the seam. It's a common mistake, and easy to fix.
Step 3: Press the Seam Allowance
Press the Seam Flat: Use your iron to press the seam allowance open if possible, or to one side if the design requires. For curved seams, pressing helps set the shape and makes the next steps easier.
Press Each Layer Individually:For a super smooth finish, press each layer of the seam allowance separately. This helps the fabric lay even flatter.
Step 4: Turn and Press the Seam
Turn Your Project Right-Side Out: Gently turn the fabric so the right side is facing out.
Roll the Seam Between Your Fingers: Use your fingers to roll the seam gently, bringing the stitch line right to the edge.
Press the Curve: With the seam rolled out, press along the curve with your iron. The mini iron is perfect here, allowing you to navigate the curve without creating new creases.
Step 5: Enjoy the Smooth Curve
Step back and admire your work! The curve should now be smooth and flat, without any puckering or bulk.
Tips & Tricks
Choose the Right Tools: Snips or small scissors with a flat tip offer better control and reduce the risk of cutting through the stitch line.
Frequency of Clips: Remember, the tighter the curve, the more frequent your clips should be. This allows the fabric to spread evenly.
Mindful Sewing Practice: Clipping and pressing seams can be a calming, mindful activity. It encourages you to slow down and focus on the details, enhancing both your skills and enjoyment.
Avoid Bulk: Clipping reduces bulk in the seam allowance, which is especially important in areas like necklines and armholes where comfort and fit are essential.
Press As You Go: Ironing isn't just for the final step. Pressing throughout the sewing process leads to a cleaner finish and makes sewing easier.
Why This Technique Enhances Your Sewing
Incorporating clipping into your sewing routine transforms your projects:
Professional Finish: Your garments will have that polished look, with smooth curves and edges.
Improved Fit and Comfort: Especially important for wearables, reducing bulk leads to better drape and comfort.
Mindful Practice: Taking the time to clip and press can make sewing a more relaxing and satisfying experience.
Clipping curved seam allowances is a small step that makes a significant difference in the quality of your sewing projects. It's a technique worth mastering, and with a bit of practice, it becomes second nature. Plus, it's a wonderful way to slow down and enjoy the sewing process—a truly mindful practice that enhances both your skills and your appreciation for the craft.
So next time you're tackling a curve, remember these steps. And if you happen to snip through the stitch line, simply re-stitch it—no stress needed. Embrace the journey of learning and watch your sewing projects shine!
Happy sewing, and may your curves always be smooth! 🧵✨
