I made these two brooches in a short course named "jewelry without metal". The name says it all, in this course we were forbidden to work with every kind of metal. I made a brooch in the form of a small cloud. This little cloud is made of stuffing to make it soft and a lot of sewing thread to give it a bit more refinement.
I also made a brooch that looks a bit like a piece of blood coral. It was made from wool and stuffing.
