Becsta, once the bread stick was cool, I just attached a small bunch of fennel fronds with a slice of onion skin. Wet the onion skin slightly to help it stick. It is really just for the photo, as it won't hold together if you move it around. I'm sure a bit of trial and error would help you come up with another idea if you want it to be sturdy!
Really love this one -thank you for sharing!
