No, this is not the jewelry I made in my concrete class, but I wish I had! This is the super fun work Belgian artist Liesbet Bussche.
Concrete class was actually canceled today due to the incredibly cold weather, but fortunately I had some materials to play with at home. It occurred to me the other day that I might have been getting too complicated with the whole mold-making thing. I figured if I just rolled out some modeling clay to a consistent thickness, I could cut circles with the cutters my friend Elena lent me, pour the concrete, let it set up and then just peel the whole thing away.
