Sunday Stitch School - Lesson 41: Thorn Stitch

Here we are again in the Biology classroom at Sunday Stitch School.
Take out your Flora and look at the Thorn Stitch.

Latin name: Suo Spinam
Japanese name: ソーンステッチ
Swedish name: Taggsöm
French name: Couchure au point d'épine

You need two threads, one to lay on the surface and another to couch it down, like this:

(Of course you can also use a braid, ribbon, wire or anything you want to couch down.)

Then couch it down with a 'cross stitch':

On the Aida sampler I used the same thread, and instead of a good contrast I got a nice 'barbed wire'!

Your
Homework
will be to add some Thorn Stitch to this sampler, which already feature X-Ray Stitch and Whipped Running Stitch.
