This idea just came to me, more like an urge of doing an owl. I was experimenting with 12mm Rivoli buttons for the eyes at first but they were not stable enough nor strong enough to withstand wire manipulation. So I had to come back to the normal rivoli. After this made I decided on making a series of brooches base on animals. First stop Bird Brooches Series.
It is made with 2 x 12mm rivoli in a oxidised silver wire setting.
