Silicone teething corners are a fun way to dress up a baby blanket or toy.  They can be attached in two different ways -- either by machine or by hand.  I will show you how to sew each one of them on to a teething blanket below. 

SEWING BY HAND

Once your teething blanket is sewn and finished, adding a teething corner will be your final step.

Making The Holes

First, you will need to punch the holes in your corner piece.  You can either use an awl or your sewing machine.  I will start with the sewing machine method.

Since you just want the sewing needle to punch holes for you, remove the thread from your needle.  I like to set my machine to the longest stitch possible.  You can see here that I used a stitch length of 5.0.

Find the curved indent line of your corner.  I am pointing to it with my seam ripper:

Align the indent end with your machine needle and put the presser foot down:

Manually turn your machine knob slowly as you let the feed dogs of the sewing machine push the corner through the needle.  Keep the indented groove lined up with the needle as you do this.  Here is the result:

You will have evenly spaced holes along the indent.  You can get the same effect with an awl, but it does take some practice to get the spacing correct.

Just press the awl all the way through the corner piece.

Sewing The Corner

Now, you are ready to sew the corner.  Start by placing the corner exactly where you want over the toy.  Be sure to push the fabric as far into the corner as possible.

While holding the corner in place with one hand, insert your threaded needle through the first hole.  I like to start from the inside of one end and then loop back around to catch it (the knot is inside the corner.)  You don't have to do it this way -- you can just go all the way through and catch the thread on the back side to knot.

Make a running stitch (up and down completely through the back) all along the holes.  You can see here where I looped the first thread and missed the hole a little bit (I will go back and correct this at the end.)  

Now, go back through and do a running stitch the other direction.

Be sure to knot the ends of the thread to secure.  (Notice that I pulled that corner thread back tight with the original thread to correct it.)   Now, the corner is securely sewn on! 

BY MACHINE

When sewing by machine, you don't have to make holes first.  IT is really a one step process.  You do have to have a steady hand because it can be easy to get out of the indented groove if you sew too fast.

Start with a threaded machine.  You will still set the stitch length to the longest setting (mine is set at 5.0.)

I've also set my machine to the slowing sewing speed (mine is a turtle speed.)

Place the corner over your fabric end.  Be sure to get the fabric tucked in as far as it will go and placed exactly where you want it to be sewn.

Line the indented and curved slot up with the machine needle and place the presser foot down.

Since it is easy to get multiple holes, I suggest you use a double stitch if you machine has it (it stitches the same stitch two times before the feed dogs move the fabric.)  If not, just be sure to leave extra thread at the beginning and end to hand tie some knots in the end of your threads.

Start sewing.  Let the feed dogs of your machine feed the corner piece through as you keep the indented edge lined up with the sewing needle.   When finished, be sure to knot the ends of the thread and trim.

Now, your corner is sewn on.

Once sewn, you are finished!  Your blanket is now ready to give to someone special and be loved!
