How To: Knife-Edge Pillow with Mitered Trim, Part II

In Part I, here, I showed you how to make a knife-edge pillow.  Knife-edge corners take the homemade look out of your pillows, by taking away the "dog ears" that happen when you sew a pillow in a perfect square.  Amazingly, sewing a perfect square does not give you a square pillow. 

Moving on to more fun stuff -- learning the skill of making mitered corners on trim.  Once you learn how to do this, you can use it in a hundred applications, from pillows to banding on drapes, and more. I figured this out myself as I am a bit obsessive when it comes to teaching myself how to make things, and I don't quit until I've figured out the best way for me to do something.  I hope you benefit from it.. If you are a novice sewer, try this with non-slippery trims and fabrics; it will save you a lot of aggravation (in other words, don't use velvet or silk).

On my 19" pillow, I wanted the box I was creating with the trim to be very visible on the front, so I attached it 3" in from the straight edge, which, with a 1/2" seam all around when the front is sewn to the back, makes the finished trim 2 1/2" in on all four sides.  There is no rule to how close to the edge you put your trim, or how close to the center you choose to put it -- that's the creative fun part!

Remember, before you start, attaching the trim comes before sewing the front to the back :).  Once the trim is applied, that's when you can assemble the pillow itself.



Supplies Needed:

Pillow front and back
Scissors
Long pins
Small ruler
Needle
Trim

1.  Lay your trim out from left to right.  Work with all your trim in one long strip  Do not cut it.  Place the trim 3" in along the straight section of  one side of the pillow front (remember, the entire length of the sides are not straight since we trimmed them in Part I).  As you lay it out, put a few pins in as I have, in that direction.  The beginning edge of the first section should be 3 1/2" inches in  from the corners when you measure with a ruler at a 45 degree angle.

2.   End the first strip by pinning the top of the trim to the fabric at the 3 1/2" point from the corner.  Now,  to make sure your mitered trim will be placed correctly and make a nice miter, fold the trim back on itself,  going left back towards the start of the trim.  This is how you are going to double check that you have the correct length of trim for the first strip and that your second strip will be 3" in down the next side.  Gently finger-press a vertical fold.

3.  Take the trim and bring it back on itself to the right and bring it down the next side,  forming the corner crease at a 45 degree angle.

4.  Double check your measurements, 3" in on the next side and 3 1/2" at the corner.  You have to do this to the second strip before you sew down the first strip so that you can achieve as perfect a square as possible.  When you are confident that your corner is placed properly, insert a pin on the bottom edge of the trim at the miter (where I put the yellow pin in the second image below).

5. With the pins in place on the first strip, start sewing on the top (the edge closest to the side of the pillow) about  a 1/2" in from the beginning edge (to allow for some adjustments, if necessary, when that raw edge becomes the final corner).  Sew the trim down close to it's edge, in a place that makes sense with the pattern of the trim.  Stop about 1/4" or less from the top pin and back stitch to secure.

6.  Do the same again on the bottom of the trim (the edge closest to the middle of the pillow).  Stitch right up to the yellow pin. Back stitch to secure.

7.  To make the first mitered corner, again fold the tape back on itself.  You will unfold it back to the right and down, just as you did in step 4 to make the corner. (I left the threads long from the stitches to show you where the stitching is, and on the lower left, the thread shows you where the inside edge of the new mitered corner will be.)

8.  Take a warm iron and press that corner down.  Make sure that the outer right side of the corner is parallel to the edge of the fabric.

9.  Once again, fold the trim back on itself, and you will see that the pressed crease is now the seam line guide for the miter.  (Fun, huh?)

 10.  If it's easier for you to see, draw over that crease with a colored pencil (be careful not to use something that will bleed through).  Stitch along the line, back stitching at the start and the end to secure.

11.  Pull the trim back and trim along the seam within 1/4".  This will help your corner lie flat.

12.  Press down the new mitered corner.  Congratulations!  Your first corner is done!

13.  Line up this new trim side 3" in from the side and pin down.  Repeat steps 2 - 4.

14.  After you have pinned down the second strip and you are ready to stitch it down, begin the stitching on the top of the trim before the first corner and continue down to the pins you've placed at the end of the second strip.  This is how you secure that corner.  Do the same on the bottom side of the trim.

15.  Repeat steps 2-4 again, and then complete the third strip.  When you get to the point where you have pressed down the third corner and you are ready to make the fourth strip to complete the square, lay the fourth  trim strip down along the last side, letting the trim overlap the beginning strip.  Cut the trim about 3 inches past that overlap.  This will leave you enough trim to complete the last corner.  Stitch the top and the bottom edges of the trim, ending both of them at the same points right to the edge of the original strip (I think you can see this pretty well in image 16).

16.  To make the fourth corner, take the remaining loose trim in your right hand, and fold the end of the fourth strip as below, making a 45 degree angle, and having the wrong side of the trim facing up at you hanging out to the right of the corner.  Press in place.  Trim the excess that's hanging off  to the right about 1/2" from the pressed edge as you did in step 11.  Machine stich around the top and the bottom of the corner.

As there is no mitered seam on this one, after you have machine stitched around the corner as in step 14, use a hand slip-stitch to sew down the seam of that miter.

17.  After a bit of work and a job well done, you are finished!  All you have to do is sew your pillow together and sit back and admire your work!

 

 I hope you can follow these directions!  While fabricating things is a strong point for me, teaching by written description is not.  Hopefully, you can make enough sense out of these steps to make it work for you.  Making mitered corners like this is not easy, so give it some patience and practice.  You'll be so happy that you did.

If you give this a go and get stuck, please send me an email at SofasandSage@gmail.com and I'll do my best to help.  If you have a question that you think others will benefit from, please post it in the comments and I will respond.

Good luck and happy sewing.

Talk to you soon,
