Couching

Couching  - I found out

And now after a week I know why I made this design: Have a look at the photo of a was-once-a-tulip

 must have been this flower which I saw several days
withering  

Don't ask me what this could be - nothing at all - a fruit maybe.
But in fact it needs not to be anything but a design
which I made first on paper.
Couching is good for round shapes
and difficult threads can be stitched down by this method.
