Sewing outward corners correctly is an essential skill in sewing, particularly for items like collars, cuffs, waistbands, pouches, and bags, where the inside often faces out. Perfecting this technique ensures your sewing projects, especially those involving corners and curved seams, have a professional finish. Here’s a detailed guide on how to achieve this:

  1. Preparing the Outward Corner:
    • Begin by sewing up to the corner. Ensure your stitching line is accurate and neat.
    • After sewing, turn the fabric so the wrong side faces out. This prepares the fabric for shaping the corner.
  2. Trimming the Seam Allowances:
    • Trim the seam allowances at the corner. This reduces bulk and helps in creating a sharp corner.
    • Be cautious to not cut too close to the stitching to avoid unraveling.
  3. Using a Point Turner for Outward Corners:
    • A point turner is a valuable tool in sewing for shaping corners and curved seams.
    • Insert the pointed end of the point turner into the outward-facing corner of the fabric.
    • Gently apply pressure to push out the corner without piercing or stretching the fabric.
    • Be extra careful with delicate fabrics like silk to avoid damage.
  4. Alternatives to a Point Turner:
    • If a point turner is not available, other items like a chopstick, the eraser end of a pencil, or an old blunt sewing machine needle can be used.
    • These tools can help in shaping the corner without compromising the fabric integrity.
  5. Pressing the Seam:
    • Pressing is a crucial final step in sewing corners and curved seams.
    • Properly press the seam to set it in place, giving a neat and finished appearance to the outward corner.
  6. Handling Different Angles:
    • The same technique applies to acute and obtuse outward corners as it does to right-angled corners.
    • Adjust the amount of trimming and the angle of turning based on the corner’s degree.
  7. Professional Finishing Touches:
    • With practice, your outward corners can have a clean, crisp, and professional look.
    • Take your time with each step to ensure accuracy and precision.
  8. Common Challenges and Solutions:
    • If the fabric puckers or the corner isn’t sharp, re-trim the seam allowance and turn the corner again.
    • For very thick fabrics, additional trimming or grading of the seam allowances might be necessary.

How To Sew Inward Corners

You should begin by stitching a straight seam along the corner so that you end up with a nice and tidy inner corner when you are finished.

The trick to successfully stitching an inner corner is to trim the seam allowances so that they are very near to the seam. The seam allowances should be a quarter of an inch. Take care not to cut the stitches while you are doing this. When you turn the cloth so that the right side is facing out, this will assist to prevent it from being rumpled.

After you have completed those steps, all that is left to do is press the corner and turn the cloth so that the correct side is facing out. You may also fasten the cloth in place by topstitching around the edge of the fabric.

You might find that there is some strain in the corner, but as long as you have snipped the seam allowance so that it is very near to the seam, everything should be alright.

This kind of stitching may be utilized not only for right angles, but also for acute and obtuse inward corners as well as straight corners. However, keep in mind that acute angles will be more difficult to sew than obtuse ones. Obtuse corners will be easier.

How To Sew Curved Seams

The ability to stitch curves is one of the fundamental sewing skills that any seamstress should be familiar with. Curved seams, particularly tight curves, can be challenging to sew, but it’s a skill that’s well worth developing anyway.

  • Precision in this step is key to ensure that the corners and curved seams look sharp and tidy once completed.

2. Trimming the Seam Allowances:

  • The next step in sewing corners and curved seams is to trim the seam allowances.
  • Trim them to about a quarter of an inch, being careful not to cut through the stitches.
  • This trimming is crucial for reducing bulk in the fabric, allowing for a smoother turn at the corner, and is especially important in corners and curved seams.

3. Turning and Shaping the Corner:

  • Carefully turn the fabric so that the right side faces out. This is a delicate process in sewing corners and curved seams.
  • Gently shape the fabric at the corner to achieve the desired angle.
  • For a sharper corner in your corners and curved seams, you might use a blunt tool like a knitting needle or a point turner.

4. Pressing for a Crisp Finish:

  • Press the sewn corner to set the seams and give it a neat, professional look.
  • Proper pressing is vital in sewing corners and curved seams as it helps the fabric lay flat and look polished.

5. Topstitching for Added Definition:

Basic Sewing Techniques To Sew Corners and Curved Seams:

Sewing curved seams can be a bit tricky, but with the right preparation and technique, it can be executed with precision and ease. Here’s a detailed guide to help you master sewing curves, ensuring your projects involving corners and curved seams have a flawless finish:

1. Marking the Curved Seam:

  • Importance of Marking: The first step in sewing corners and curved seams is to mark the seam line on the fabric. This serves as a crucial reference point for accuracy.
  • Choosing the Right Marker: Opt for a specialized fabric marker that creates fine, temporary lines. Ensure the marker is suitable for ironing over without leaving permanent marks.
  • Creating a Continuous Curve: Use a seam gauge or a small ruler to make small dashes along the seam line. Connect these dashes to form a continuous, smooth curve. Accurate marking is key in sewing corners and curved seams to perfection.

2. Pinning and Preparing to Sew:

  • Securing the Fabric: Before sewing, pin the fabric along the marked line. This step prevents the fabric from shifting and ensures a more precise outcome in sewing corners and curved seams.
  • Selecting Stitch Length: For sewing curves, use a shorter stitch length, around 2, or 2.5 for denser fabrics. This provides better control and flexibility for the fabric.

3. Press The Seam After You Are Done Stitching It

Because of this, working with the cloth and achieving a clean finish will be much simpler.

  • Importance of Correct Pressing: After stitching your curved seam, pressing it properly is vital. This step helps in achieving a crisp and clean finish, essential for professional-looking corners and curved seams.
  • Avoiding Stretching: Curved seams, not being on the straight grain, are prone to stretching. It’s important to press the seam with an up-and-down motion rather than sliding the iron back and forth.
  • Technique for Pressing: Work in small sections, pressing each part carefully. This method ensures that the fabric doesn’t stretch out of shape, maintaining the integrity of your corners and curved seams.

4. Trimming the Seam Allowances:

  • Crucial for Curved Seams: Trimming the seam allowances is especially important when sewing corners and curved seams. It reduces bulk and helps the fabric lay flat and smooth along the curves.
  • Recommended Size: The ideal size for seam allowances in corners and curved seams is about a quarter of an inch (or five millimeters). This width allows enough fabric for durability while reducing excess bulk.
  • Handling Tight Curves: For very tight curves in your corners and curved seams, you may need to trim the seam allowances even smaller. This ensures that the fabric can turn and lie flat without puckering or bunching.
  • Consistency is Key: Ensure that the trimming is even and consistent along the length of the seam for a uniform look in your corners and curved seams.

Making Concave Curves:

  • Common Use: Concave curves are found in areas like necklines and armholes of garments.
  • Clipping the Seam Allowances: To ease the tension along the seam and allow the fabric to lie flat, clip the seam allowances at regular intervals. These clips should be perpendicular to the stitching line but be careful not to cut into the actual seam.
  • Frequency of Clipping: The sharper the curve of the seam, the more clips you’ll need to make. This allows the fabric to spread and adjust to the curve, essential in sewing corners and curved seams.

Making Convex Curves:

  • Typical Use: Convex curves are often used for decorative edges on blankets and pillows.
  • Notching the Seam Allowances: Unlike concave curves, convex curves require notching. Cut small triangles (notches) out of the seam allowances along the seam. This removes excess fabric, allowing the seam to lay flat and preventing the curve from puckering.
  • Frequency of Notching: As with clipping, the frequency of notching depends on the steepness of the curve. Tighter curves require more frequent notching.

5. Finishing The Curved Seam

  • Pressing: Once you’ve turned the fabric so that the right side is out, press the curved seam. This step is crucial for setting the seam and creating a flat, smooth edge, which is vital for corners and curved seams.
  • Topstitching: To further define and secure the seam, topstitching along the seam can be beneficial. This not only adds a decorative touch but also helps in maintaining the shape of the curve, which is especially important in corners and curved seams.

6. Sewing Together Opposing Curves:

  • Understanding the Challenge: Joining a concave curve to a convex curve, like setting sleeves or color-blocked garment sections, can be tricky but is a common requirement in sewing corners and curved seams.
  • Reducing Seam Allowance: Use a smaller seam allowance, such as 1/4 inch, for easier alignment of the opposing curves.
  • Marking Midpoints: Mark the midpoint of each curve, either with a fabric marker or a small snip. Align these points first when pinning the pieces together.
  • Methodical Pinning: Start by pinning the midpoints, then pin the edges, and finally, fill in between. Pin perpendicular to the seam line for better control while sewing.
  • Slow and Steady Sewing: Sew the seam at a slow pace to ensure accuracy. The slower you sew, the more control you’ll have, reducing the likelihood of mistakes in your corners and curved seams.
  • Pressing the Seam: Press the seams towards the side with the convex curve. This helps in laying the fabric flat and achieving a neat finish in corners and curved seams.

Tips for Working with Curved Seams:

  • Practice Scrap Fabric: Before attempting your final project, practice these techniques on scrap fabric to perfect your skill in sewing corners and curved seams.
  • Patience is Crucial: Take your time with each step, especially with challenging curves. This ensures precision in your corners and curved seams.
  • Use Appropriate Tools: Sharp scissors, proper pins, and a reliable sewing machine can make a significant difference in the outcome of your corners and curved seams.
