Copper, pencil crayons, resin. I still need to attach the pin back.
This is very much an experiment. I love the colours I get with resin over pencil crayons but am not confident of the wearability. I thought riveting it might secure it, and a second layer of copper would add depth, but the drilling and riveting actually started to lift the resin off the pencil crayon layer. Also the way I did the drilling several of the holes got large enough that I'm not confident about the rivets holding the piece together.
Pouring the resin over a flat piece had its challenges too. Without a lip to contain the resin it slightly overflowed in two places. I found it didn't coat evenly, added a second layer, and ended up with definate lines and dimples in the resin.
Despite all its flaws I am very fond of this piece. I am looking forward to wearing it.
