This beautiful stitch is the Pueblo Stitch. This is the latest stitch I have learned on my 100 Stitches project.
I found this stitch in the book Embroidery Stitches by Mary Webb. My version looks a bit different because she used a two-ply twisted wool thread that is split while stitching but I am using two separate perle cotton threads in contrasting colors:
This is a decorative line stitch, I worked this from left to right, however Embroidery Stitches shows the line worked from right to left.
The first step is to come up through the fabric:
Go back into the fabric a little to the right of where the needle first emerged. Since I am using two threads, I needed to make sure to have them spread apart on either side of the needle so that they will "split" the stitch and give the correct twisted appearance: Come back out of the fabric right next to the spot where the needle first emerged:
pull all the way through:
Now bring the needle around for the next stitch. Go into the fabric a little to the right from the first stitch:
Set up your threads - to add the twist, change the thread positions. The thread that was on top now is on the bottom. In my case, the first stitch had the brown thread on the top and the creamy pink on the bottom. for the next stitch I made the creamy pink on top and the brown on the bottom:
Pull all the way through to form the second stitch:
Bring the needle around and arrange the threads to start the third stitch:
I continued like this until the end of the stitching line and ended by going back into the fabric right at the final stitch:
I secured my thread underneath by weaving it between a couple of stitches:
Here is the completed line of stitching:
