100 Stitches - Knotted Insertion Stitch

Time to show the latest stitch I have learned on my 100 Stitches journey.  This lovely stitch is the Knotted Insertion Stitch:
 

This is an insertion stitch and just like the Buttonhole Insertion and Twisted Insertion Stitches,

the purpose of the stitch is to hold two pieces of fabric together:

To set up this stitch, I took two pieces of fabric, and folded an edge under on each piece.  This is just for my demonstration, if I were doing this on a project, I would have hemmed each edge!   I lined the two pieces of fabric up on a piece of stiff paper:

I spaced them about 1/4" apart and then stitched the fabric to the stiff paper with some white pearl cotton floss:

To stitch the stitch, I used some different pearl cotton floss, this pretty blue - this is color variations #4025 by DMC.

I knotted the end of the floss and came through the fabric in the folded over edge.  This will hide the knot:

Then I pulled the floss all the way through:

Now according to 100 Stitches, this is just making Buttonhole Stitches on the edge of the fabric, alternating side to side and adding a second stitch over the loops.  So I set up my needle just like a Buttonhole Stitch.  I went into the fabric and came back out right on the folded edge.  I didn't go through both layers of fabric just the top layer.  I pulled the needle all the way through and passed over the working thread:

This left me with two threads - one on the top and one emerging from the fold:

Next, I brought the needle around and under the two threads:






























I went under those two threads but over the working thread - this makes a sort of loop:

I kept pulling and a knot began to form:

Done! 

Now I went to the opposite side and do the same steps: set up like a Buttonhole Stitch:

Pull through:

Bring the needle around and go under the two threads:

but over the working thread:

and pull through to form the knot:

Then back to the opposite side and start again:

I just kept stitching on alternate sides:



until I was at the end of the fabric.  100 Stitches didn't explain how to finish this, so I just went back into the fold of the fabric at the end and tied a small knot to secure my floss.

Then I cut away the stitches that were holding the fabric to the paper and admired the finished stitching!

I really enjoyed learning how to do this stitch.  I think it is so beautiful.  
This stitch is in the Insertion Stitches category and is #100 on the 100 Stitches list.  I didn't do these stitches in any sort of order, so I am not finished with the list yet - I still have 22 more stitches to learn!
