It took a little less than ten metres of the gold thread, and the couching thread was used in two different colours, which is much more visible in the original than in the picture. It looks a little wonky in the picture because I digressed from the pre-drawn pattern during the embroidering, and it's much harder to do a straight line if there is no leading line on the fabric. Why did I digress?
I made one single drawing, but you can see that I tested two different possiblilities - one was letting the three leaves run together close to the band (as can be seen in the upper left part), the other leaving a gap between the leaves. Same applies to the leaves where they touch the band - bottom with a gap, top without. I like the gaps between the parts better than the run-together look, so the final version will have a gap between the single elements.
And here's how the backside of the embroidery looks:
You can see the different colours of the couching thread much better here - though the rest, obviously, is by far not as spectacular...
