Overall styling concept

Since the theme is the sound of flowers, I wanted to gather these flower brooches and make the whole in the shape of a flower bush.

The ‘flower stems’ can be made from metal tubing and held in place at the bottom with a metal or wooden base (I prefer wood, it will have a more natural look to it). In this way the brooches can be inserted directly into it, and the whole serves as an ornament as well as brooch storage.

I also conceived the idea of making the ‘stems’ curved so that I could also add some foliage. I don't know how to achieve this yet though, still need to research and experiment.
