Upcycle recycled jewelry

Today the neighbourhood christmas market is taking place again (feels like last years' market was only a month ago...). I've been crafting to fill our daughters' stand with original things to sell (next to the toys they've selected from their own collection).  Not all pins sold out last year, so as a last minute project I turned the pins into necklaces, inspired by this image. I'm going to keep one for myself, I think. Can't decide whether it's going to be the bird ('klein koketje') or the mackerel.
