This months lesson is all about Curves and Corners.  Many times when you are reading a sewing tutorial or a sewing pattern the instructions will say something like “clip curves” or “notch corners”.  This is a VERY important step in getting your fabric to lay correctly when you are finished and should not be skipped.

But what does it mean to clip a curve?

Today I will talk about 3 different techniques. Inner Curves, Outer Curves and Corners. Up first Corners:

The first thing to remember when sewing corners is to make sure that you keep your seam allowances consistent.  This will give you a sharp edge on your corner.

When you are sewing and you get to the point where you need to turn a corner,

how to pivot needle

Put your needle down and raise your presser foot.  On my Bernina 710 I can set the machine to do this automatically for me when I tap on the back of my presser foot. It’s a huge time saver!

With your needle down pivot your fabric and continue sewing.

After you are done sewing cut off the corners of your fabric at 45 degree angles to your seams.  This is necessary to reduce bulk in the corners so that they will lie flat.

Next take a tool that has a pointed yet dull end and push it into the corner to push it out.  You can also use a piece of cardboard cut in a square to push the corner out.

Once your corner is pushed out and squared up, press it well to hold it in place.

Next: Inner Curves

You will most likely find inner curves when sewing collars and some pockets.

First thing, make sure your seam allowance is consistent throughout the curve as you are sewing. I find it helpful to use my presser foot as a reference point.

After you are done sewing, clip the curve close to the seam (but don’t clip the seam) about every 1/4”-1/2”.  This will allow the fabric to fold over on itself when turned right side out.

Last up: Outer Curves.

I think that we run into outer curves most frequently when sewing.  You will find them  in bags, curved corners on pockets, peter pan collars and many other places.

The example I’m showing you here is a curved seam on a simple zippered pouch.

how to notch a curve

After you have sewn your seam, again being careful to keep your seam allowances consistent, clip v shaped notches into your seam allowance. Clip them about every 1/4”.  Be careful not to clip through your seam but if you do don’t fret you can just sew over it again.

In the case of the zip pouch I made, I clipped notches around the entire perimeter before I turned it right side out.

Do not skip these steps!!!  Otherwise your seam allowance will get in the way of your fabric lying flat and you will not have a nice curve, or any curve at all for that matter!

  1. I just recently purchased a Bernina 710. Can you explain the setting for ‘tapping the back of the presser foot’? Thanks.

    1. Sure!
      On the main screen touch the icon that looks like gears.
      Then touch the icon that looks like a stitching line and button hole.
      Then touch the arrow in the lower right corner.
      Then touch the presserfoot icon. This will set the pivot foot tap.
      Hope this helps!

      1. Wow!!!
        Didn’t know about the pivot setting! Thanks for helping me with that. Just got the 710 this fall and still learning. Our Bernina dealer is 2 hours away so I haven’t taken the classes with the holidays and 4 busy school aged kids but I am missing out on tips like this by not doing this!
        Thanks for this tip! Maybe u could be my online teacher 🙂

  2. Thank you very much for this sewing lesson. I don’ t have much experience with curves but I am looking forward to having more success when I do them.

    Could you share where you got the wooden corner turner (not sure what you call it).
