The base row is backstitch and then the loop stitches are formed around the backstitches.
In the first two rows I have worked a single row of back stitch and I rather like the look of these two rows.
The third row has two rows of back stitch and then the loop stitches are worked between these two rows.
In the last one I have worked two lots of three rows of back stitch separated by a couple of rows of linen thread.
I then did the loop stitches over the three rows of back stitch which formed two braid like rows of Pekinese stitch.
I then laced them together in the lime green thread.
I know this looks different from Sharon's sample but this is how I interpreted the lacing when I read the Batsford Encyclopedia of Embroidery Stitches that I borrowed from the Embroiderers Guild Library.
To me it looks upside down to Sharon's but I don't think the Stitch Police will come and take me away--well I hope not anyway.
I have used a linen fabric and Perle cottons.
