Easy Mitered Corners!

Start with a small mitered corner application to gain confidence in making excellent mitered corners every time!

To start gather notions and fabric scraps to practice :

My square measures 8 1/2 inches, and the 4 strips are 1 1/2 x 12 inches. Take special note here: when making mitered corners your strip length needs to be much longer than your square, the wider your strip, the more length you need. Usually I add the strip width times two, plus an extra inch or two, for peace of mind. When I was doing this the first time on my tree skirt, I ended up making my first round of border half the width to accommodate the miter — it wasn’t long enough for the width.

On with the instructions:

DSC_0140

pin your strips, center on your square, on opposite sides

DSC_0141

Sew with 1/4″ seam — I don’t reinforce my seams at all, it may be helpful to pull out a few stitches when setting the miter.

I press open here to cut down on bulk

DSC_0143

pin and sew opposite sides borders to the square

DSC_0144

Press open again

Fold your square on the diagonal, this works for rectangles too, but you would need to do one corner at a time.

DSC_0147

Match up your seams, making sure that the corner is lying flat without excess, and pin

DSC_0148

This is how I pin, you don’t want the seams to move, and you need your tails to be secure as well

DSC_0149

You can do both corners at once, just flip it over for the opposite corner

Next line up your ruler on the diagonal, and mark the sewing line on the tail, like so —

DSC_0151

And sew on the line that you drew

DSC_0153

Open up your square to check your corner

DSC_0154

If you are pleased, trim to 1/4″ seam allowance, and press, if it’s not quite right just pull out your stitches and try again. Take your time lining things up :)

Now go back and fold in the opposite diagonal and repeat

DSC_0156

I like to trim up the extended seam allowances

You should have 4 of these!

Mitered Corner Tutorial

So far I’ve used this technique for my tree skirt, and a few swap blocks. I envision throw pillows on the couch as the perfect project for mitered corners. Maybe that will be next :)

I think that’s everything! Let me know if you have any questions and I will do my best to answer them :) Have a great weekend!

    Thanks Amy. I’ll bookmark it and perhaps I’ll actually do mitered corners sometime. I have done them in the past…many years ago…with great frustration! I shall not give up.

    I don't ever miter my corners because I've never really known how! So thanks for this tutorial! I hope you don't mind if I share a link to this tutorial on sewwhattoday.blogspot.com on March 4!

    This is the easiest way to do mitered corners I have done and I have tried many. I use the formula of “Measure the length of your square plus the width of your boarder doubled”.

    Great tutorial. I now will conquer the dreaded mitred corner. Your pdf of instructions will not print. Would like to have a print out – easier to follow at the sewing machine. Thank you.

    the trouble I have is keeping corners mitered while hemming border. Mitered corners look ‘so’ professional and I have so much trouble with them. I guess they’re so simple ; they’re hard.

    formula for strip lengths is length of side plus 2 x width of strip plus 2x seam allowance. Eg IG block is 6″ and strip will be finished width 1 inch (I.e. 1 and 1/4 cut) then length is 6 + 2 + 1/2 = 8 1/2″

    Both my son and my youngest daughter are tall–and sleep on XL Twin beds. Unfortunately, ready-made XL twin sheets are extremely hard to find. When I do find them, they’re ugly or plain. I’ve attempted to make twin XL fitted sheets out of nice fabric–but the sheets have been too short on the sides–or the corners didn’t fit right. After reading this tutorial yesterday, I started to wonder if I could use your method for making mitered corners on my XL Twin fitted sheets. What do you think? Thank you for posting this, btw. I really appreciate it! <3

    So easy and I was even too lazy to read the whole thing. I myself tend to be a look at the pictures and wing it kind of gal. Came out beautifully. Thank you so much for teaching this method.

    Forgot to mention it was on a king size quilt with a 4″ border.

    Hi Amy,
    great post, thanks.

    I assume this technique will work with borders?? Have you done it?
    Thanks

    • Amy August 15, 2017 at 1:02 pm - Reply

      Absolutely it works for borders! I scaled down my sample so it would be easy to photograph :) I’ve used this method many times.
