Tutorial — Mitered Corners


Posted on April 3rd, by Amy in Tutorial. 40 comments

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. I don’t have a formula here, but when in doubt make it longer :) 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:

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

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

pin and sew opposite sides borders to the square

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.

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

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

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 –

And sew on the line that you drew

Open up your square to check your corner

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

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!

  18. 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”.

  19. 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.

  20. excelente tutorial es muy bueno saber elaborar las costura perfectas por eso aprendo de las mejores, gracias por compartir saludos desde venezuela……..

  21. 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.

  22. Many thanks for this great tutorial! Found it on pinterest and it will help me a lot in all my future sewing projects ;-)
    Have a fabulous week!
