Have You Ever Wondered How to go around a square corner using a bias binding foot?

This article shows you how to put mitre corners on your quilts with your sewing machine the easy way!

Since putting the binding on a mitre corner relates to quilts, I will focus this article on how to finish a quilt using bias binding AND have the corners mitred. Hopefully, you will find this helpful!

What Does “Mitre” (or “Miter”) Actually Mean?

The definition of the word “Mitre” refers to a joint.

According to Wikipedia, a mitre joint (spell “miter” in North America) is a joint made by beveling each of two parts to be joined, usually at a 45 degree angle, to form a corner, usually at a 90 degree angle.

When referring to fining a quilt with binding – there are two ways of binding square corners (1) mitre (2) butt-join.

The look of “mitred” is by far most popular, but most people assume that it is the more difficult method.I was certainly intimidated when I first started, but once I’d got the hang of it, one method really isn’t more difficult than the other.
So, which way is better: Mitred or Butted?
Functionally, they are both going to hold up :-)
That means the decision is mainly based on personal preference.

In most cases, to determine whether you’d finish you binding by the mitered or butted method, simply take a look at how the border of the quilt was put together:

  • Was the corner of the border butted?
  • Or was it mitered?
  • Does it look better one way or the other?

Your decision is easy to make from there.


Now, if you use a Bias Binding Foot and
Wonder HOW to go around Square Corners…

I’d have to admit that I wondered the same thing.

While I LOVE using my Bias Binding foot, I’ve always done my quilt binding in the traditional “Two Step” way (since I also cut my quilt bindings in STRAIGHT grain).

For me, the bias binding foot has been used for actual BIAS bindings on clothing (i.e. going around necklines and armholes) and other household items such as place mat, apron and bibs. These things normally has curved corners and I haven’t had to figure out how to do miter corners with these….

Nevertheless, it occurred to me that a lot of people DO want to use this foot to bind their quilts – that means being able to go over a SQUARE corner becomes an absolute necessity. Oh my.

And for the life of me, there is hardly ANY information around. I’ve hunted high and low for a method that I’m actually happy enough to use myself. I think I found more questions than answers….

Until I came across this:

Who knew? This video was made by none other than Janome themselves.

Sure, the foot they use is different (it is a width-specific, non-adjustable, cone-shape, industrial-style attachment, which means you’d need different ones for EACH different binding widths), but the principles are the same.

After a bit of trial-and-error, I’ve figured out what worked for me :-)

*** Ugly Demo Sample Warning: for the purpose of this demo, I used a quilted piece of calico that has red thread on the front and black thread on the back to show you the different sides. Also using a cream thread on red binding***


First, I ran a zig-zag stitch around the raw edge of my quilted-but-un-bound quilt ), so that the layers are flattened to make it easier to feed into the plastic slot of the foot. For this step, you can overlock the edges if you prefer.

Second, thread your prepared binding into the foot and adjust the slot into the correct width of the binding so that it is a snug fit.

Then feed your prepared quilt into the slot, encasing the raw edge into the binding and stitch all the way to the corner (be sure to finish EXACTLY at the edge), then back stitch and cut the thread.

Next I lifted the presser foot and pulled the quilt out just far enough, leaving just the bias binding in the foot. I turn the quilt corner by 90 degrees and fold the bias binding around the corner as shown in the second video.

How Did it Go Again? Let’s See it Step-by-Step:

1. This is what your piece looks like when you pull it out of the foot.

2. Open the fold, then turn this opened up binding 90 degrees towards the next edge

3. This is what it looks like on the BACK.
Make sure the edge of your quilt lines up with the fold line of the binding

4. Then fold the FRONT half over, wrapping the edge of your quilt

5. Use a pin or clip to hold the mitre fold in place.
You can give it a quick shot of steam from your iron to set the fold. 

NOTE: I often take the pin out once the fold is set. 
Because I find it easier to get it back into the foot without the pin.

Carefully position this directly under your needle, and lower your needle into the exact spot where your mitre fold starts. Back stitch in that spot a couple of times then sew on as per normal until you reach the next corner.

And, this is what the back looks like before you put the foot back to the machine.

Voila! Perfectly mitred corners by bias binding foot. This is the FRONT.

And this is the BACK.
Please forgive me for the messy work – the point was to show you how this method works, at the last minute I just whipped together something really quickly so you can (hopefully) see what I mean :-)

A bit of Disclaimer here:

This method works on quilts with low-loft battings which are flatter and thinner (and NOT with battings with high loft, which are thick and fluffy). Because you DO need to feed the whole quilt sandwich into the slot of your binding foot. See photo.

Also, many quilters still prefer to bind their quilts in the traditional, TWO-Step Method, as opposed to a ONE-Step Method (shown here) which is more commonly seen in production*. We will cover more of these two methods in another article.

While it may seem fiddly at first, you will find that you DO save time overall by stitching just once to catch all layers – with the help of the adjustable bias binding foot – and just paying a bit of attention each time you get to the corner (there are only four corners in most cases anyway).
