Whipped Back Stitch

Time for a new stitch on my 100 Stitches Plus list.  This is the Whipped Back Stitch.  

This stitch is composed of a line of Back Stitches that is then whipped with a contrasting or same colored floss.  For my stitch, I am using a contrasting color floss.  

I stitched the line of Back Stitch in dark brown perle cotton floss.  
For the whipping, I used this beautiful blue perle cotton floss:

Whipping a line of stitching is very easy.  To begin, I brought the needle up through the fabric above the first Back Stitch:

I pulled the floss all the way through.  Next, I brought the needle around and slid the needle under the next Back Stitch.  Notice the needle is not going into or picking up any fabric, it is just sliding atop the fabric and under the stitching line:

I pulled until all the floss had passed under the stitch.  

Then I brought the needle around to slide under the next Back Stitch.  The whipping is always done in the same direction:

all along the line of stitching.  When I reached the final Back Stitch, I went back into the fabric right above the final stitch:

I pulled the needle all the way through and secured the floss on the underside of the fabric:

So simple and such a beautiful stitch! 

I found this stitch in the book Embroidery Stitches by Mary Webb.
