Digging in the garden, I made an almost archeological discovery, an old bolt eaten by rust. I cleaned it a bit, not too much for the patina to remain and, as I found it really beautiful, I decided to find another use for it.
I turned it into a seal by electro-etching a man hole cover pattern on his head.
And the result is perfectly functional as you can see.
This is how to turn rubbish into design and original object 🙂
