is a made up of three parallel rows of Chain Stitch, that are then buttonholed together into a textured 'braid'.
You can see and read more about this Italian stitch here, at Italian Needlework. Also check out Stitches Stories.
Work it like this:
Stitch three parallel columns of Chain Stitch.
Next, turn the work to get three horisontal rows of Chain Stitch.
Use Buttonhole Stitch to join the chains.
I have used a different colour to clarify how to stitch, but you can use the same colour (green).
I have also used only one stitch to make the instructions clear.
For the proper stitch, add more Buttonhole Stitches, (see the blue Buttonhole stitches below).
Continue to join the middle and lower Chain Stitches together, work from down to up.
Here I have joined the Chains with groups of three blue Buttonhole Stitches.
When worked in the same coloured thread, you get a nice textured braid.
Don't you think it looks like crochet?
Add Parma Stitch to these three samplers.
